Simplifying -1(1 + -7r) + -1r = 6r + -18 (1 * -1 + -7r * -1) + -1r = 6r + -18 (-1 + 7r) + -1r = 6r + -18 Combine like terms: 7r + -1r = 6r -1 + 6r = 6r + -18 Reorder the terms: -1 + 6r = -18 + 6r Add '-6r' to each side of the equation. -1 + 6r + -6r = -18 + 6r + -6r Combine like terms: 6r + -6r = 0 -1 + 0 = -18 + 6r + -6r -1 = -18 + 6r + -6r Combine like terms: 6r + -6r = 0 -1 = -18 + 0 -1 = -18 Solving -1 = -18 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.
