Simplifying 2(q + -4) = 4q + -1(2q + 4) Reorder the terms: 2(-4 + q) = 4q + -1(2q + 4) (-4 * 2 + q * 2) = 4q + -1(2q + 4) (-8 + 2q) = 4q + -1(2q + 4) Reorder the terms: -8 + 2q = 4q + -1(4 + 2q) -8 + 2q = 4q + (4 * -1 + 2q * -1) -8 + 2q = 4q + (-4 + -2q) Reorder the terms: -8 + 2q = -4 + 4q + -2q Combine like terms: 4q + -2q = 2q -8 + 2q = -4 + 2q Add '-2q' to each side of the equation. -8 + 2q + -2q = -4 + 2q + -2q Combine like terms: 2q + -2q = 0 -8 + 0 = -4 + 2q + -2q -8 = -4 + 2q + -2q Combine like terms: 2q + -2q = 0 -8 = -4 + 0 -8 = -4 Solving -8 = -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.
