Simplifying -2x + 13 = -2(x + -7) Reorder the terms: 13 + -2x = -2(x + -7) Reorder the terms: 13 + -2x = -2(-7 + x) 13 + -2x = (-7 * -2 + x * -2) 13 + -2x = (14 + -2x) Add '2x' to each side of the equation. 13 + -2x + 2x = 14 + -2x + 2x Combine like terms: -2x + 2x = 0 13 + 0 = 14 + -2x + 2x 13 = 14 + -2x + 2x Combine like terms: -2x + 2x = 0 13 = 14 + 0 13 = 14 Solving 13 = 14 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.
