Simplifying -12w + -18 = 2(-6w + 7) Reorder the terms: -18 + -12w = 2(-6w + 7) Reorder the terms: -18 + -12w = 2(7 + -6w) -18 + -12w = (7 * 2 + -6w * 2) -18 + -12w = (14 + -12w) Add '12w' to each side of the equation. -18 + -12w + 12w = 14 + -12w + 12w Combine like terms: -12w + 12w = 0 -18 + 0 = 14 + -12w + 12w -18 = 14 + -12w + 12w Combine like terms: -12w + 12w = 0 -18 = 14 + 0 -18 = 14 Solving -18 = 14 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.
