Simplifying 11x + -2(x + -2) = 9(x + 1) + 3 Reorder the terms: 11x + -2(-2 + x) = 9(x + 1) + 3 11x + (-2 * -2 + x * -2) = 9(x + 1) + 3 11x + (4 + -2x) = 9(x + 1) + 3 Reorder the terms: 4 + 11x + -2x = 9(x + 1) + 3 Combine like terms: 11x + -2x = 9x 4 + 9x = 9(x + 1) + 3 Reorder the terms: 4 + 9x = 9(1 + x) + 3 4 + 9x = (1 * 9 + x * 9) + 3 4 + 9x = (9 + 9x) + 3 Reorder the terms: 4 + 9x = 9 + 3 + 9x Combine like terms: 9 + 3 = 12 4 + 9x = 12 + 9x Add '-9x' to each side of the equation. 4 + 9x + -9x = 12 + 9x + -9x Combine like terms: 9x + -9x = 0 4 + 0 = 12 + 9x + -9x 4 = 12 + 9x + -9x Combine like terms: 9x + -9x = 0 4 = 12 + 0 4 = 12 Solving 4 = 12 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.
