Simplifying 2(x + -2) + 1 = 2x + -2 Reorder the terms: 2(-2 + x) + 1 = 2x + -2 (-2 * 2 + x * 2) + 1 = 2x + -2 (-4 + 2x) + 1 = 2x + -2 Reorder the terms: -4 + 1 + 2x = 2x + -2 Combine like terms: -4 + 1 = -3 -3 + 2x = 2x + -2 Reorder the terms: -3 + 2x = -2 + 2x Add '-2x' to each side of the equation. -3 + 2x + -2x = -2 + 2x + -2x Combine like terms: 2x + -2x = 0 -3 + 0 = -2 + 2x + -2x -3 = -2 + 2x + -2x Combine like terms: 2x + -2x = 0 -3 = -2 + 0 -3 = -2 Solving -3 = -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.
