Answer

There is no solution.

Solution

Let's solve the equation: \[ \frac{x}{x-6} + 5 = \frac{6}{x-6} \] **Step 1: Combine the terms over a common denominator.** \[ \frac{x}{x-6} + 5 = \frac{6}{x-6} \] Subtract \(\frac{x}{x-6}\) from both sides: \[ 5 = \frac{6}{x-6} - \frac{x}{x-6} \] Combine the fractions: \[ 5 = \frac{6 - x}{x-6} \] **Step 2: Clear the denominator by multiplying both sides by \(x - 6\).** \[ 5(x - 6) = 6 - x \] Expand the left side: \[ 5x - 30 = 6 - x \] **Step 3: Solve for \(x\).** Add \(x\) to both sides: \[ 6x - 30 = 6 \] Add \(30\) to both sides: \[ 6x = 36 \] Divide by \(6\): \[ x = 6 \] **Step 4: Check for validity.** The original equation has denominators \(x - 6\), so \(x\) cannot be \(6\). However, our solution is \(x = 6\), which is not allowed. **Conclusion:** There is no valid solution to the equation. **Answer:** **B. There is no solution.**

Bonus Knowledge

To solve the equation \( \frac{x}{x-6}+5=\frac{6}{x-6} \), we can start by getting a common denominator. Rearranging gives us \( \frac{x + 5(x-6)}{x-6} = \frac{6}{x-6} \). Simplifying further, we have \( \frac{x + 5x - 30}{x-6} = \frac{6}{x-6} \), which means \( \frac{6x - 30}{x-6} = \frac{6}{x-6} \). Cross-multiplying results in \( 6x - 30 = 6 \). Thus, \( 6x = 36 \) gives us \( x = 6 \). However, when we substitute \( x = 6 \) back into the original equation, it leads to division by zero (denominator becomes zero), which means \( x = 6 \) is not a valid solution. Therefore, the correct choice is B. There is no solution. If you love thinking about bizarre cases, this situation is quite unique! It's always a good reminder that some equations have boundaries marked by those pesky denominators. It's like riding a roller coaster—make sure the safety bar is secure, or else! Keep an eye out for those vertical asymptotes; they can really throw a wrench in your solving plans.
