Simplifying -2x + -9 = -2(x + 4) Reorder the terms: -9 + -2x = -2(x + 4) Reorder the terms: -9 + -2x = -2(4 + x) -9 + -2x = (4 * -2 + x * -2) -9 + -2x = (-8 + -2x) Add '2x' to each side of the equation. -9 + -2x + 2x = -8 + -2x + 2x Combine like terms: -2x + 2x = 0 -9 + 0 = -8 + -2x + 2x -9 = -8 + -2x + 2x Combine like terms: -2x + 2x = 0 -9 = -8 + 0 -9 = -8 Solving -9 = -8 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.
