Simplifying 4(x + 3) = -7(6 + 2x) + 18x Reorder the terms: 4(3 + x) = -7(6 + 2x) + 18x (3 * 4 + x * 4) = -7(6 + 2x) + 18x (12 + 4x) = -7(6 + 2x) + 18x 12 + 4x = (6 * -7 + 2x * -7) + 18x 12 + 4x = (-42 + -14x) + 18x Combine like terms: -14x + 18x = 4x 12 + 4x = -42 + 4x Add '-4x' to each side of the equation. 12 + 4x + -4x = -42 + 4x + -4x Combine like terms: 4x + -4x = 0 12 + 0 = -42 + 4x + -4x 12 = -42 + 4x + -4x Combine like terms: 4x + -4x = 0 12 = -42 + 0 12 = -42 Solving 12 = -42 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.
