Simplifying 2x + 84 = 2x + 12 Reorder the terms: 84 + 2x = 2x + 12 Reorder the terms: 84 + 2x = 12 + 2x Add '-2x' to each side of the equation. 84 + 2x + -2x = 12 + 2x + -2x Combine like terms: 2x + -2x = 0 84 + 0 = 12 + 2x + -2x 84 = 12 + 2x + -2x Combine like terms: 2x + -2x = 0 84 = 12 + 0 84 = 12 Solving 84 = 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.
