X=10
X=-10
X=-5
X=5

Answer 1

The first one is x=10

Answer 2

`\boxed{x = 10}`

Explanation:

`= > 2x + 12 = - 2(4 - 2x) \\ \\ = > 2x + 12 = (( - 2) * 4) - (( - 2) * 2x) \\ \\ = > 2x + 12 = - 8 - ( - 4x) \\ \\ = > 2x + 12 = - 8 + 4x \\ \\ = > 2x - 4x + 12 = - 8 \\ \\ = > - 2x + 12 = - 8 \\ \\ = > - 2x = - 8 - 12 \\ \\ = > \cancel{-} 2x = \cancel{- }20 \\ \\ = > 2x = 20 \\ \\ = > x = (20)/(2) \\ \\ = > x = 10`
