Simplifying 2(x + -9) = 2x + 1 Reorder the terms: 2(-9 + x) = 2x + 1 (-9 * 2 + x * 2) = 2x + 1 (-18 + 2x) = 2x + 1 Reorder the terms: -18 + 2x = 1 + 2x Add '-2x' to each side of the equation. -18 + 2x + -2x = 1 + 2x + -2x Combine like terms: 2x + -2x = 0 -18 + 0 = 1 + 2x + -2x -18 = 1 + 2x + -2x Combine like terms: 2x + -2x = 0 -18 = 1 + 0 -18 = 1 Solving -18 = 1 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.
