Simplifying -7(y + 3) = -2(y + 3) + -5y Reorder the terms: -7(3 + y) = -2(y + 3) + -5y (3 * -7 + y * -7) = -2(y + 3) + -5y (-21 + -7y) = -2(y + 3) + -5y Reorder the terms: -21 + -7y = -2(3 + y) + -5y -21 + -7y = (3 * -2 + y * -2) + -5y -21 + -7y = (-6 + -2y) + -5y Combine like terms: -2y + -5y = -7y -21 + -7y = -6 + -7y Add '7y' to each side of the equation. -21 + -7y + 7y = -6 + -7y + 7y Combine like terms: -7y + 7y = 0 -21 + 0 = -6 + -7y + 7y -21 = -6 + -7y + 7y Combine like terms: -7y + 7y = 0 -21 = -6 + 0 -21 = -6 Solving -21 = -6 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.
