Answer 3

It seems like there might be a misunderstanding or error in your equation. Let's break down what you've written:

9(x - 15) = 72

To solve for x, you can follow these steps:

1. Distribute the 9 on the left side of the equation: 9x - 9 * 15 = 72

2. Simplify the equation by performing the multiplication on the left side: 9x - 135 = 72

3. Add 135 to both sides of the equation to isolate the variable (x) on the left side: 9x - 135 + 135 = 72 + 135

4. This simplifies to: 9x = 207

5. Finally, divide both sides by 9 to solve for x: (9x)/9 = 207/9

6. Simplify: x = 23

So, the solution to the equation is x = 23.
