Introduction

In the realm of mathematics, solving for an unknown variable is a fundamental skill. This article delves into the process of solving for u in the equation 4 + u/8.96 = 11. We will break down the steps involved, providing a clear and concise explanation for anyone looking to enhance their algebraic problem-solving abilities. This detailed guide will not only walk you through the solution but also provide insights into the underlying mathematical principles. Understanding these principles will empower you to tackle similar problems with confidence. So, let's embark on this mathematical journey together and unlock the value of u.

Understanding the Equation

The equation we aim to solve is 4 + u/8.96 = 11. This is a linear equation in one variable, where u represents the unknown we need to find. Linear equations are characterized by having the variable raised to the power of 1, and they form the backbone of many mathematical and scientific applications. To successfully solve this equation, we need to isolate u on one side of the equation. This involves performing algebraic operations that maintain the equality of both sides. The key principle here is that whatever operation we perform on one side of the equation, we must also perform on the other side to keep the equation balanced. This ensures that the value of u we obtain is indeed the correct solution. Let's dive deeper into the steps required to isolate u and find its value.

Step-by-Step Solution

Step 1: Isolate the Term with 'u'

To begin, our goal is to isolate the term containing u, which is u/8.96. To achieve this, we need to eliminate the constant term 4 from the left side of the equation. We can do this by subtracting 4 from both sides of the equation. This maintains the balance of the equation and brings us closer to isolating u.

  • Original equation: 4 + u/8.96 = 11
  • Subtract 4 from both sides: 4 + u/8.96 - 4 = 11 - 4
  • Simplified equation: u/8.96 = 7

Now, we have successfully isolated the term with u on one side of the equation. This is a crucial step in solving for u, as it allows us to focus on the remaining operation needed to find its value.

Step 2: Solve for 'u'

Now that we have u/8.96 = 7, the next step is to isolate u completely. To do this, we need to undo the division by 8.96. We can achieve this by multiplying both sides of the equation by 8.96. Remember, whatever operation we perform on one side, we must perform on the other to maintain the equality.

  • Current equation: u/8.96 = 7
  • Multiply both sides by 8.96: (u/8.96) * 8.96 = 7 * 8.96
  • Simplified equation: u = 7 * 8.96

By multiplying both sides by 8.96, we have successfully isolated u on the left side of the equation. Now, we simply need to perform the multiplication on the right side to find the value of u.

Step 3: Calculate the Value of 'u'

To find the value of u, we need to perform the multiplication 7 * 8.96. This is a straightforward arithmetic calculation that will give us the numerical value of u. Let's carry out the multiplication:

  • u = 7 * 8.96
  • u = 62.72

Therefore, the value of u that satisfies the equation 4 + u/8.96 = 11 is 62.72. We have now successfully solved for u by following the steps of isolating the term with u, multiplying both sides by the appropriate value, and performing the final calculation.

Verification

To ensure our solution is correct, it's always a good practice to verify it. We can do this by substituting the value we found for u back into the original equation and checking if it holds true. This step is crucial in confirming that we haven't made any errors in our calculations.

  • Original equation: 4 + u/8.96 = 11
  • Substitute u = 62.72: 4 + 62.72/8.96 = 11
  • Calculate 62.72/8.96: 62.72/8.96 = 7
  • Substitute back into the equation: 4 + 7 = 11
  • Simplify: 11 = 11

Since the equation holds true after substituting the value of u, we can confidently conclude that our solution is correct. This verification step provides a final confirmation that we have successfully solved for u.
