Simplifying 2x + -1 = 2(x + -2) Reorder the terms: -1 + 2x = 2(x + -2) Reorder the terms: -1 + 2x = 2(-2 + x) -1 + 2x = (-2 * 2 + x * 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.
