H2: Unveiling the Equation: A Detailed Breakdown
To effectively solve for 'n' in the equation n + 1 = 4(n - 8), we need to systematically dissect the equation and apply the correct algebraic principles. This section will provide a detailed breakdown of each step, ensuring clarity and comprehension. The first crucial step involves understanding the distributive property. This property states that a(b + c) = ab + ac. In our equation, we have 4(n - 8), which means we need to multiply 4 by both 'n' and '-8'. This gives us 4 * n = 4n and 4 * -8 = -32. So, 4(n - 8) expands to 4n - 32. Now our equation looks like this: n + 1 = 4n - 32. The next step involves isolating the variable 'n' on one side of the equation. To do this, we need to move all terms containing 'n' to one side and all constant terms to the other side. We can start by subtracting 'n' from both sides of the equation. This cancels out the 'n' on the left side, leaving us with 1 = 4n - n - 32. Simplifying this, we get 1 = 3n - 32. Now we need to move the constant term, -32, to the left side of the equation. We do this by adding 32 to both sides. This gives us 1 + 32 = 3n - 32 + 32. Simplifying this, we get 33 = 3n. Finally, to isolate 'n', we need to divide both sides of the equation by 3. This gives us 33 / 3 = 3n / 3. Simplifying this, we get 11 = n. Therefore, the solution to the equation n + 1 = 4(n - 8) is n = 11. We can verify this solution by substituting n = 11 back into the original equation. This gives us 11 + 1 = 4(11 - 8), which simplifies to 12 = 4(3), and further simplifies to 12 = 12. Since both sides of the equation are equal, our solution is correct.
H2: Step-by-Step Solution: A Practical Guide
Let's embark on a step-by-step journey to solve the equation n + 1 = 4(n - 8). This practical guide will provide clear instructions, making the process easy to follow. Remember, the key to solving algebraic equations is to maintain balance. Whatever operation you perform on one side of the equation, you must perform the same operation on the other side. This ensures that the equation remains equivalent throughout the solving process. Our starting point is the equation: n + 1 = 4(n - 8). The first step involves applying the distributive property. This property allows us to eliminate the parentheses by multiplying the term outside the parentheses by each term inside the parentheses. In our case, we need to multiply 4 by both 'n' and '-8'. This gives us: 4 * n = 4n and 4 * -8 = -32. So, the equation now becomes: n + 1 = 4n - 32. The next step is to gather all the 'n' terms on one side of the equation and the constant terms on the other side. A common strategy is to move the 'n' term from the left side to the right side. We can do this by subtracting 'n' from both sides of the equation: n + 1 - n = 4n - 32 - n. This simplifies to: 1 = 3n - 32. Now, we need to move the constant term, -32, to the left side of the equation. We can do this by adding 32 to both sides: 1 + 32 = 3n - 32 + 32. This simplifies to: 33 = 3n. The final step is to isolate 'n' by dividing both sides of the equation by the coefficient of 'n', which is 3: 33 / 3 = 3n / 3. This simplifies to: 11 = n. Therefore, the solution to the equation n + 1 = 4(n - 8) is n = 11. This step-by-step approach ensures clarity and precision in solving the equation. By following these steps, you can confidently solve similar linear equations.
H2: Verification: Ensuring the Accuracy of Our Solution
After solving an equation, it's crucial to verify the solution to ensure accuracy. In this section, we will demonstrate how to verify our solution, n = 11, for the equation n + 1 = 4(n - 8). Verification involves substituting the calculated value of 'n' back into the original equation. If the left-hand side (LHS) of the equation equals the right-hand side (RHS) after the substitution, then our solution is correct. Let's start with the original equation: n + 1 = 4(n - 8). We substitute n = 11 into the equation: 11 + 1 = 4(11 - 8). Now, we simplify both sides of the equation separately. On the left-hand side (LHS), we have: 11 + 1 = 12. On the right-hand side (RHS), we first simplify the expression inside the parentheses: 11 - 8 = 3. Then, we multiply 4 by 3: 4 * 3 = 12. So, the right-hand side (RHS) also equals 12. Now, we compare the LHS and RHS: LHS = 12 and RHS = 12. Since the LHS equals the RHS, our solution, n = 11, is verified. This verification process confirms that our solution is accurate and satisfies the original equation. Verification is an essential step in problem-solving, as it helps to catch any errors made during the solving process. By verifying your solutions, you can build confidence in your problem-solving abilities and ensure the correctness of your answers. In conclusion, by substituting n = 11 back into the original equation, we have shown that both sides of the equation are equal, thus verifying that n = 11 is indeed the correct solution to n + 1 = 4(n - 8).
H2: Common Mistakes to Avoid: A Guide to Error-Free Solving
Solving equations can be tricky, and it's easy to make mistakes along the way. This section will highlight some common mistakes to avoid when solving equations like n + 1 = 4(n - 8). By being aware of these pitfalls, you can improve your accuracy and problem-solving skills. One of the most common mistakes is mishandling the distributive property. Remember, when you have a term multiplying an expression in parentheses, you must multiply the term by every term inside the parentheses. For example, in 4(n - 8), you need to multiply 4 by both 'n' and '-8'. A common error is to multiply 4 only by 'n' and forget to multiply it by '-8'. Another frequent mistake is combining unlike terms. You can only add or subtract terms that have the same variable and exponent. For example, you can combine 4n and -n, but you cannot combine 4n and -32. Make sure you only combine like terms to avoid errors. Sign errors are also a common source of mistakes. Pay close attention to the signs of the terms when moving them from one side of the equation to the other. Remember, when you move a term across the equals sign, you need to change its sign. For example, if you have -32 on the right side of the equation, when you move it to the left side, it becomes +32. Another mistake is forgetting to perform the same operation on both sides of the equation. Remember, the key to solving equations is to maintain balance. Whatever operation you perform on one side of the equation, you must perform the same operation on the other side. For example, if you subtract 'n' from the left side, you must also subtract 'n' from the right side. Finally, not verifying the solution is a common mistake. Always substitute your solution back into the original equation to check if it's correct. This will help you catch any errors you may have made during the solving process. By being mindful of these common mistakes and taking steps to avoid them, you can improve your accuracy and confidence in solving equations. Solving n + 1 = 4(n - 8), or any similar equation, requires careful attention to detail and a solid understanding of algebraic principles. By avoiding these pitfalls, you'll be well on your way to mastering equation solving.
