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