Simplifying 2(x + 5) = 2x + -9 Reorder the terms: 2(5 + x) = 2x + -9 (5 * 2 + x * 2) = 2x + -9 (10 + 2x) = 2x + -9 Reorder the terms: 10 + 2x = -9 + 2x Add '-2x' to each side of the equation. 10 + 2x + -2x = -9 + 2x + -2x Combine like terms: 2x + -2x = 0 10 + 0 = -9 + 2x + -2x 10 = -9 + 2x + -2x Combine like terms: 2x + -2x = 0 10 = -9 + 0 10 = -9 Solving 10 = -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.
