Simplifying -1x + 12 = -1x + 30 Reorder the terms: 12 + -1x = -1x + 30 Reorder the terms: 12 + -1x = 30 + -1x Add 'x' to each side of the equation. 12 + -1x + x = 30 + -1x + x Combine like terms: -1x + x = 0 12 + 0 = 30 + -1x + x 12 = 30 + -1x + x Combine like terms: -1x + x = 0 12 = 30 + 0 12 = 30 Solving 12 = 30 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.
