Question

How do you solve `5x + 2 = 2x - 10`?

Answer 1

`x=-4`

Explanation:

`5x + 2 = 2x -10`

Start by subtracting `2x` from both sides

`5x + 2 - 2x = 2x - 10 - 2x`

`3x + 2 = -10`

Add `-2` on both sides

`3x + 2 - 2 = -10 -2`

`3x = -12`

Divide both sides by `3`

`(3x)/3 = (-12)/3`

`x = -4`
