Simplifying 3(x + 3) = 3x + 4 + 3 Reorder the terms: 3(3 + x) = 3x + 4 + 3 (3 * 3 + x * 3) = 3x + 4 + 3 (9 + 3x) = 3x + 4 + 3 Reorder the terms: 9 + 3x = 4 + 3 + 3x Combine like terms: 4 + 3 = 7 9 + 3x = 7 + 3x Add '-3x' to each side of the equation. 9 + 3x + -3x = 7 + 3x + -3x Combine like terms: 3x + -3x = 0 9 + 0 = 7 + 3x + -3x 9 = 7 + 3x + -3x Combine like terms: 3x + -3x = 0 9 = 7 + 0 9 = 7 Solving 9 = 7 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.
