Simplifying 3(x + 9) + 7 = 3x + 9 Reorder the terms: 3(9 + x) + 7 = 3x + 9 (9 * 3 + x * 3) + 7 = 3x + 9 (27 + 3x) + 7 = 3x + 9 Reorder the terms: 27 + 7 + 3x = 3x + 9 Combine like terms: 27 + 7 = 34 34 + 3x = 3x + 9 Reorder the terms: 34 + 3x = 9 + 3x Add '-3x' to each side of the equation. 34 + 3x + -3x = 9 + 3x + -3x Combine like terms: 3x + -3x = 0 34 + 0 = 9 + 3x + -3x 34 = 9 + 3x + -3x Combine like terms: 3x + -3x = 0 34 = 9 + 0 34 = 9 Solving 34 = 9 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.
