Simplifying 4(x + 3) + -9 = 2x + 2(1 + x) Reorder the terms: 4(3 + x) + -9 = 2x + 2(1 + x) (3 * 4 + x * 4) + -9 = 2x + 2(1 + x) (12 + 4x) + -9 = 2x + 2(1 + x) Reorder the terms: 12 + -9 + 4x = 2x + 2(1 + x) Combine like terms: 12 + -9 = 3 3 + 4x = 2x + 2(1 + x) 3 + 4x = 2x + (1 * 2 + x * 2) 3 + 4x = 2x + (2 + 2x) Reorder the terms: 3 + 4x = 2 + 2x + 2x Combine like terms: 2x + 2x = 4x 3 + 4x = 2 + 4x Add '-4x' to each side of the equation. 3 + 4x + -4x = 2 + 4x + -4x Combine like terms: 4x + -4x = 0 3 + 0 = 2 + 4x + -4x 3 = 2 + 4x + -4x Combine like terms: 4x + -4x = 0 3 = 2 + 0 3 = 2 Solving 3 = 2 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.
