Simplifying 3x + 2 + -1x = 12 + 2x Reorder the terms: 2 + 3x + -1x = 12 + 2x Combine like terms: 3x + -1x = 2x 2 + 2x = 12 + 2x Add '-2x' to each side of the equation. 2 + 2x + -2x = 12 + 2x + -2x Combine like terms: 2x + -2x = 0 2 + 0 = 12 + 2x + -2x 2 = 12 + 2x + -2x Combine like terms: 2x + -2x = 0 2 = 12 + 0 2 = 12 Solving 2 = 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.
