Question

Solve −2x − 15 = 6x + 9.

Answer 1

Answer:
`x=-3`

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:

`(-24)/(8)=(8x)/(8)\\\\x=-3`
