Simplifying 3(x + 2) + -9 = 5x + -2(2 + x) Reorder the terms: 3(2 + x) + -9 = 5x + -2(2 + x) (2 * 3 + x * 3) + -9 = 5x + -2(2 + x) (6 + 3x) + -9 = 5x + -2(2 + x) Reorder the terms: 6 + -9 + 3x = 5x + -2(2 + x) Combine like terms: 6 + -9 = -3 -3 + 3x = 5x + -2(2 + x) -3 + 3x = 5x + (2 * -2 + x * -2) -3 + 3x = 5x + (-4 + -2x) Reorder the terms: -3 + 3x = -4 + 5x + -2x Combine like terms: 5x + -2x = 3x -3 + 3x = -4 + 3x Add '-3x' to each side of the equation. -3 + 3x + -3x = -4 + 3x + -3x Combine like terms: 3x + -3x = 0 -3 + 0 = -4 + 3x + -3x -3 = -4 + 3x + -3x Combine like terms: 3x + -3x = 0 -3 = -4 + 0 -3 = -4 Solving -3 = -4 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.
