Simplifying 4y + 7 = 2(2y + -4) Reorder the terms: 7 + 4y = 2(2y + -4) Reorder the terms: 7 + 4y = 2(-4 + 2y) 7 + 4y = (-4 * 2 + 2y * 2) 7 + 4y = (-8 + 4y) Add '-4y' to each side of the equation. 7 + 4y + -4y = -8 + 4y + -4y Combine like terms: 4y + -4y = 0 7 + 0 = -8 + 4y + -4y 7 = -8 + 4y + -4y Combine like terms: 4y + -4y = 0 7 = -8 + 0 7 = -8 Solving 7 = -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.
