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