Simplifying 3(6x + 7) = 9(2x + 3) Reorder the terms: 3(7 + 6x) = 9(2x + 3) (7 * 3 + 6x * 3) = 9(2x + 3) (21 + 18x) = 9(2x + 3) Reorder the terms: 21 + 18x = 9(3 + 2x) 21 + 18x = (3 * 9 + 2x * 9) 21 + 18x = (27 + 18x) Add '-18x' to each side of the equation. 21 + 18x + -18x = 27 + 18x + -18x Combine like terms: 18x + -18x = 0 21 + 0 = 27 + 18x + -18x 21 = 27 + 18x + -18x Combine like terms: 18x + -18x = 0 21 = 27 + 0 21 = 27 Solving 21 = 27 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.
