Simplifying 8x + -1(8x + -7) = 67 Reorder the terms: 8x + -1(-7 + 8x) = 67 8x + (-7 * -1 + 8x * -1) = 67 8x + (7 + -8x) = 67 Reorder the terms: 7 + 8x + -8x = 67 Combine like terms: 8x + -8x = 0 7 + 0 = 67 7 = 67 Solving 7 = 67 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.
