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