Simplifying 2(3x + -9) = 6(x + -9) Reorder the terms: 2(-9 + 3x) = 6(x + -9) (-9 * 2 + 3x * 2) = 6(x + -9) (-18 + 6x) = 6(x + -9) Reorder the terms: -18 + 6x = 6(-9 + x) -18 + 6x = (-9 * 6 + x * 6) -18 + 6x = (-54 + 6x) Add '-6x' to each side of the equation. -18 + 6x + -6x = -54 + 6x + -6x Combine like terms: 6x + -6x = 0 -18 + 0 = -54 + 6x + -6x -18 = -54 + 6x + -6x Combine like terms: 6x + -6x = 0 -18 = -54 + 0 -18 = -54 Solving -18 = -54 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.
