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