Simplifying 4(x + 1) = 2(2x + -4) Reorder the terms: 4(1 + x) = 2(2x + -4) (1 * 4 + x * 4) = 2(2x + -4) (4 + 4x) = 2(2x + -4) Reorder the terms: 4 + 4x = 2(-4 + 2x) 4 + 4x = (-4 * 2 + 2x * 2) 4 + 4x = (-8 + 4x) Add '-4x' to each side of the equation. 4 + 4x + -4x = -8 + 4x + -4x Combine like terms: 4x + -4x = 0 4 + 0 = -8 + 4x + -4x 4 = -8 + 4x + -4x Combine like terms: 4x + -4x = 0 4 = -8 + 0 4 = -8 Solving 4 = -8 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.
