Simplifying -4x + 12 + 2x = -2(x + 15) Reorder the terms: 12 + -4x + 2x = -2(x + 15) Combine like terms: -4x + 2x = -2x 12 + -2x = -2(x + 15) Reorder the terms: 12 + -2x = -2(15 + x) 12 + -2x = (15 * -2 + x * -2) 12 + -2x = (-30 + -2x) Add '2x' to each side of the equation. 12 + -2x + 2x = -30 + -2x + 2x Combine like terms: -2x + 2x = 0 12 + 0 = -30 + -2x + 2x 12 = -30 + -2x + 2x Combine like terms: -2x + 2x = 0 12 = -30 + 0 12 = -30 Solving 12 = -30 Couldn't find a variable to solve for. This equation is invalid, the left and right sides are not equal, therefore there is no solution.
