Simplifying 19 + -2x = -1(2x + -9) Reorder the terms: 19 + -2x = -1(-9 + 2x) 19 + -2x = (-9 * -1 + 2x * -1) 19 + -2x = (9 + -2x) Add '2x' to each side of the equation. 19 + -2x + 2x = 9 + -2x + 2x Combine like terms: -2x + 2x = 0 19 + 0 = 9 + -2x + 2x 19 = 9 + -2x + 2x Combine like terms: -2x + 2x = 0 19 = 9 + 0 19 = 9 Solving 19 = 9 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.
