Simplifying 8(2x + 7) = 16x + -9 Reorder the terms: 8(7 + 2x) = 16x + -9 (7 * 8 + 2x * 8) = 16x + -9 (56 + 16x) = 16x + -9 Reorder the terms: 56 + 16x = -9 + 16x Add '-16x' to each side of the equation. 56 + 16x + -16x = -9 + 16x + -16x Combine like terms: 16x + -16x = 0 56 + 0 = -9 + 16x + -16x 56 = -9 + 16x + -16x Combine like terms: 16x + -16x = 0 56 = -9 + 0 56 = -9 Solving 56 = -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.
