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