Simplifying -12(0.5 + 0.5y) + 6y = -7 (0.5 * -12 + 0.5y * -12) + 6y = -7 (-6 + -6y) + 6y = -7 Combine like terms: -6y + 6y = 0 -6 + 0 = -7 -6 = -7 Solving -6 = -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.
