Simplifying -2x + -8 = 7 + -2(x + -3) Reorder the terms: -8 + -2x = 7 + -2(x + -3) Reorder the terms: -8 + -2x = 7 + -2(-3 + x) -8 + -2x = 7 + (-3 * -2 + x * -2) -8 + -2x = 7 + (6 + -2x) Combine like terms: 7 + 6 = 13 -8 + -2x = 13 + -2x Add '2x' to each side of the equation. -8 + -2x + 2x = 13 + -2x + 2x Combine like terms: -2x + 2x = 0 -8 + 0 = 13 + -2x + 2x -8 = 13 + -2x + 2x Combine like terms: -2x + 2x = 0 -8 = 13 + 0 -8 = 13 Solving -8 = 13 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.
