Simplifying 9(x + 1) + 2 = 5x + 4(3 + x) Reorder the terms: 9(1 + x) + 2 = 5x + 4(3 + x) (1 * 9 + x * 9) + 2 = 5x + 4(3 + x) (9 + 9x) + 2 = 5x + 4(3 + x) Reorder the terms: 9 + 2 + 9x = 5x + 4(3 + x) Combine like terms: 9 + 2 = 11 11 + 9x = 5x + 4(3 + x) 11 + 9x = 5x + (3 * 4 + x * 4) 11 + 9x = 5x + (12 + 4x) Reorder the terms: 11 + 9x = 12 + 5x + 4x Combine like terms: 5x + 4x = 9x 11 + 9x = 12 + 9x Add '-9x' to each side of the equation. 11 + 9x + -9x = 12 + 9x + -9x Combine like terms: 9x + -9x = 0 11 + 0 = 12 + 9x + -9x 11 = 12 + 9x + -9x Combine like terms: 9x + -9x = 0 11 = 12 + 0 11 = 12 Solving 11 = 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.
