Simplifying (w + 5) = (w + -7) Reorder the terms: (5 + w) = (w + -7) Remove parenthesis around (5 + w) 5 + w = (w + -7) Reorder the terms: 5 + w = (-7 + w) Remove parenthesis around (-7 + w) 5 + w = -7 + w Add '-1w' to each side of the equation. 5 + w + -1w = -7 + w + -1w Combine like terms: w + -1w = 0 5 + 0 = -7 + w + -1w 5 = -7 + w + -1w Combine like terms: w + -1w = 0 5 = -7 + 0 5 = -7 Solving 5 = -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.
