Simplifying 8(x + -2) + -4 = 4(2x + -3) Reorder the terms: 8(-2 + x) + -4 = 4(2x + -3) (-2 * 8 + x * 8) + -4 = 4(2x + -3) (-16 + 8x) + -4 = 4(2x + -3) Reorder the terms: -16 + -4 + 8x = 4(2x + -3) Combine like terms: -16 + -4 = -20 -20 + 8x = 4(2x + -3) Reorder the terms: -20 + 8x = 4(-3 + 2x) -20 + 8x = (-3 * 4 + 2x * 4) -20 + 8x = (-12 + 8x) Add '-8x' to each side of the equation. -20 + 8x + -8x = -12 + 8x + -8x Combine like terms: 8x + -8x = 0 -20 + 0 = -12 + 8x + -8x -20 = -12 + 8x + -8x Combine like terms: 8x + -8x = 0 -20 = -12 + 0 -20 = -12 Solving -20 = -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.
