Simplifying 6x + -2(-6 + 3x) = 7 6x + (-6 * -2 + 3x * -2) = 7 6x + (12 + -6x) = 7 Reorder the terms: 12 + 6x + -6x = 7 Combine like terms: 6x + -6x = 0 12 + 0 = 7 12 = 7 Solving 12 = 7 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.
