#### Answer

x=-6

#### Work Step by Step

Simplifying
4x = 2x + -12
Reorder the terms:
4x = -12 + 2x
Solving
4x = -12 + 2x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2x' to each side of the equation.
4x + -2x = -12 + 2x + -2x
Combine like terms: 4x + -2x = 2x
2x = -12 + 2x + -2x
Combine like terms: 2x + -2x = 0
2x = -12 + 0
2x = -12
Divide each side by '2'.
x = -6
Simplifying
x = -6
