x=-6

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
