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