Simplifying 9(2x + -9) = 3(6x + 2) Reorder the terms: 9(-9 + 2x) = 3(6x + 2) (-9 * 9 + 2x * 9) = 3(6x + 2) (-81 + 18x) = 3(6x + 2) Reorder the terms: -81 + 18x = 3(2 + 6x) -81 + 18x = (2 * 3 + 6x * 3) -81 + 18x = (6 + 18x) Add '-18x' to each side of the equation. -81 + 18x + -18x = 6 + 18x + -18x Combine like terms: 18x + -18x = 0 -81 + 0 = 6 + 18x + -18x -81 = 6 + 18x + -18x Combine like terms: 18x + -18x = 0 -81 = 6 + 0 -81 = 6 Solving -81 = 6 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.
