Simplifying -2(y + 4) = 20 + -2y + -12 Reorder the terms: -2(4 + y) = 20 + -2y + -12 (4 * -2 + y * -2) = 20 + -2y + -12 (-8 + -2y) = 20 + -2y + -12 Reorder the terms: -8 + -2y = 20 + -12 + -2y Combine like terms: 20 + -12 = 8 -8 + -2y = 8 + -2y Add '2y' to each side of the equation. -8 + -2y + 2y = 8 + -2y + 2y Combine like terms: -2y + 2y = 0 -8 + 0 = 8 + -2y + 2y -8 = 8 + -2y + 2y Combine like terms: -2y + 2y = 0 -8 = 8 + 0 -8 = 8 Solving -8 = 8 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.
