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