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