Simplifying -7(4 + y) = -5y + -2y + -3 (4 * -7 + y * -7) = -5y + -2y + -3 (-28 + -7y) = -5y + -2y + -3 Reorder the terms: -28 + -7y = -3 + -5y + -2y Combine like terms: -5y + -2y = -7y -28 + -7y = -3 + -7y Add '7y' to each side of the equation. -28 + -7y + 7y = -3 + -7y + 7y Combine like terms: -7y + 7y = 0 -28 + 0 = -3 + -7y + 7y -28 = -3 + -7y + 7y Combine like terms: -7y + 7y = 0 -28 = -3 + 0 -28 = -3 Solving -28 = -3 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.
