Answer: x=-3

Step-by-step explanation:

Given the equation:

-2x - 15 = 6x + 9

You must solve for "x" to find its value.

You can follow these steps:

- Add 2x to both sides of the equation:

-2x - 15+2x= 6x + 9+2x

- 15 = 8x +9

- Subtract 9 from both sides of the equation:

- 15-9 = 8x +9-9

-24 = 8x

- Divide both sides of the equation by 8. Then you get:

\frac{-24}{8}=\frac{8x}{8}\\\\x=-3
