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