Simplifying 7(y + -4) + y = 2(6 + 4y) Reorder the terms: 7(-4 + y) + y = 2(6 + 4y) (-4 * 7 + y * 7) + y = 2(6 + 4y) (-28 + 7y) + y = 2(6 + 4y) Combine like terms: 7y + y = 8y -28 + 8y = 2(6 + 4y) -28 + 8y = (6 * 2 + 4y * 2) -28 + 8y = (12 + 8y) Add '-8y' to each side of the equation. -28 + 8y + -8y = 12 + 8y + -8y Combine like terms: 8y + -8y = 0 -28 + 0 = 12 + 8y + -8y -28 = 12 + 8y + -8y Combine like terms: 8y + -8y = 0 -28 = 12 + 0 -28 = 12 Solving -28 = 12 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.
