Simplifying 3(x + 2) + 1 = 5x + -2(-1 + x) Reorder the terms: 3(2 + x) + 1 = 5x + -2(-1 + x) (2 * 3 + x * 3) + 1 = 5x + -2(-1 + x) (6 + 3x) + 1 = 5x + -2(-1 + x) Reorder the terms: 6 + 1 + 3x = 5x + -2(-1 + x) Combine like terms: 6 + 1 = 7 7 + 3x = 5x + -2(-1 + x) 7 + 3x = 5x + (-1 * -2 + x * -2) 7 + 3x = 5x + (2 + -2x) Reorder the terms: 7 + 3x = 2 + 5x + -2x Combine like terms: 5x + -2x = 3x 7 + 3x = 2 + 3x Add '-3x' to each side of the equation. 7 + 3x + -3x = 2 + 3x + -3x Combine like terms: 3x + -3x = 0 7 + 0 = 2 + 3x + -3x 7 = 2 + 3x + -3x Combine like terms: 3x + -3x = 0 7 = 2 + 0 7 = 2 Solving 7 = 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.
