Simplifying 4(2x + -9) = 8(x + -4) Reorder the terms: 4(-9 + 2x) = 8(x + -4) (-9 * 4 + 2x * 4) = 8(x + -4) (-36 + 8x) = 8(x + -4) Reorder the terms: -36 + 8x = 8(-4 + x) -36 + 8x = (-4 * 8 + x * 8) -36 + 8x = (-32 + 8x) Add '-8x' to each side of the equation. -36 + 8x + -8x = -32 + 8x + -8x Combine like terms: 8x + -8x = 0 -36 + 0 = -32 + 8x + -8x -36 = -32 + 8x + -8x Combine like terms: 8x + -8x = 0 -36 = -32 + 0 -36 = -32 Solving -36 = -32 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.
