Simplifying 4(2 + -1x) = 2(1 + -2x) (2 * 4 + -1x * 4) = 2(1 + -2x) (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.
