Simplifying -1 + -1(2 + y) = -1(4 + y) -1 + (2 * -1 + y * -1) = -1(4 + y) -1 + (-2 + -1y) = -1(4 + y) Combine like terms: -1 + -2 = -3 -3 + -1y = -1(4 + y) -3 + -1y = (4 * -1 + y * -1) -3 + -1y = (-4 + -1y) Add 'y' to each side of the equation. -3 + -1y + y = -4 + -1y + y Combine like terms: -1y + y = 0 -3 + 0 = -4 + -1y + y -3 = -4 + -1y + y Combine like terms: -1y + y = 0 -3 = -4 + 0 -3 = -4 Solving -3 = -4 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.
