Remember, the key to success in algebra, and in mathematics in general, is practice. The more problems you solve, the more comfortable and confident you'll become.

Now, let's look at the equation $5p - 14 = 8p + 4$. Our primary goal is to isolate 'p' on one side of the equation. To do this, we need to gather all terms involving 'p' on one side and the constant numbers on the other side. This is achieved through a series of algebraic manipulations, ensuring that we maintain the equation's balance. Each step we take is based on fundamental algebraic principles, such as the addition and subtraction properties of equality. This means that whatever we do to one side of the equation, we must also do to the other side to keep the equation balanced. By following these principles, we can systematically transform the equation into a form where 'p' stands alone, revealing its value. This methodical approach is the core of solving algebraic equations and is applicable to a wide range of problems, making it a valuable skill to master. We will always begin with simple steps, building our way to the solution so that you understand the process. No steps will be skipped!

Step-by-Step Solution

Alright, let's jump right in and solve for 'p': $5p - 14 = 8p + 4$.

Step 1: Combine 'p' terms

First, we want to get all the 'p' terms on one side of the equation. We can do this by subtracting $5p$ from both sides. This eliminates the $5p$ term on the left side: $5p - 14 - 5p = 8p + 4 - 5p$. This simplifies to $-14 = 3p + 4$. The idea here is to keep the equation balanced. If we do something to one side, we must do the same to the other side. Think of it like a seesaw. If you add or remove weight from one side, you have to do the same to the other side to keep it level. This fundamental principle ensures that the equation remains valid throughout the solution process. We chose to subtract $5p$ from both sides, but we could have also subtracted $8p$ from both sides. The key is to choose the operation that will allow you to consolidate the 'p' terms on one side.

Step 2: Isolate the 'p' term

Next, we need to isolate the term with 'p'. To do this, we'll subtract $4$ from both sides of the equation: $-14 - 4 = 3p + 4 - 4$. This simplifies to $-18 = 3p$. By subtracting 4 from both sides, we successfully removed the constant term from the side with the 'p' term. Again, remember that every step is taken to maintain the balance of the equation, and this allows us to move closer to isolating 'p'. This step also reinforces the basic principle of inverse operations. Subtraction is the inverse of addition, and by using it, we undo the addition of $4$ to the $3p$ term. These inverse operations are the building blocks of solving for a variable.

Step 3: Solve for 'p'

Finally, to solve for 'p', we need to get 'p' all by itself. We do this by dividing both sides of the equation by $3$: $-18 / 3 = 3p / 3$. This gives us $-6 = p$. So, the solution is $p = -6$. Division is the inverse of multiplication, and in this step, we use it to eliminate the coefficient in front of 'p'. Dividing both sides by 3 isolates 'p', giving us the final solution. The solution is obtained through systematic application of inverse operations, which reverses the effects of the operations performed on 'p' in the original equation. We can now confidently say that we have successfully solved for the variable 'p'!

Verification of the Solution

Always, always check your work! Let's substitute $p = -6$ back into the original equation to make sure our solution is correct: $5(-6) - 14 = 8(-6) + 4$. Simplifying, we get $-30 - 14 = -48 + 4$, which simplifies to $-44 = -44$. Since both sides are equal, our solution $p = -6$ is correct. This is called the verification step. It is a critical component of problem-solving. It checks your work to ensure that you have not made any errors during the calculations. If the two sides of the equation are not equal after substitution, then you know there's a mistake in your calculations. This step improves accuracy and boosts confidence in your answer. Never skip the verification step; it is the final quality check.

Tips and Tricks for Solving Equations

• Practice Regularly: The more you solve equations, the more familiar you'll become with the process. Practice makes perfect, and with each problem, you'll gain confidence and speed. Try different types of equations to expand your knowledge. Remember that different types of equations may require different approaches, but the basic principles of solving them always remain the same. The key is to recognize patterns and apply the appropriate strategies. Regular practice will help you hone your problem-solving skills and develop a deeper understanding of the concepts.
• Write Down Every Step: Don't skip steps, especially when you're starting. Writing each step down helps you avoid mistakes and keeps your work organized. This also makes it easier to review your work and identify any errors. The process of writing down each step forces you to think through the problem logically and systematically. This methodical approach is the foundation of successful problem-solving, not just in algebra but in many other areas of life.
• Double-Check Your Work: Always verify your solution by plugging it back into the original equation. This is a simple but effective way to catch any errors you might have made. This step is as important as the solving itself. By double-checking, you can build confidence in your answers and ensure that they are accurate. This also reinforces your understanding of the equation and its components. Checking your work not only helps you find mistakes but also builds your problem-solving skills.
• Understand the Concepts: Don't just memorize the steps. Make sure you understand why you're doing each step. Understanding the underlying principles will help you solve more complex problems. Concepts like the properties of equality and inverse operations are crucial. If you understand these concepts, you'll be able to solve various equation types, even those you've never encountered before. Understanding is much more valuable than memorization. It gives you the ability to adapt to new situations and use your knowledge effectively.
• Use Visual Aids: Drawing diagrams or using online tools can sometimes help visualize the problem, especially when you are dealing with equations. Visual aids can clarify concepts that might be difficult to grasp through numbers alone. This can be especially helpful for learners who are more visually inclined. Using these tools to help break down complex problems into smaller, more manageable parts can boost your understanding and make the problem-solving process more enjoyable.

Common Mistakes to Avoid

• Forgetting to Apply Operations to Both Sides: Always remember that whatever you do to one side of the equation, you must do to the other side. This is the cornerstone of keeping the equation balanced. This is a common mistake and often leads to an incorrect answer. If the equation isn't balanced, the solution will not be valid. Making sure you always apply the same operations to both sides of the equation will prevent you from making this mistake and ensure the accuracy of your solutions.
• Miscalculating with Negative Numbers: Be careful with your calculations, especially when dealing with negative numbers. Double-check your arithmetic to avoid errors. Negative numbers can trip up even experienced mathematicians. Carefully review each step of your calculations to ensure you have not made any mistakes. You may consider rewriting the problem to make sure the negative signs are properly placed. Practice using negative numbers in various operations to improve your comfort and accuracy.
• Not Simplifying: Always simplify your answer. Combine like terms wherever possible. Simplifying makes the solution easier to understand and reduces the likelihood of further errors. This also helps in the verification process. A simplified equation will make it easier to plug in your solution and verify its accuracy. Learning the skill of simplification will not only help you solve the problem but also provide a deeper understanding of mathematics.
