Simplifying 4(2x + -7) = 8(x + -2) Reorder the terms: 4(-7 + 2x) = 8(x + -2) (-7 * 4 + 2x * 4) = 8(x + -2) (-28 + 8x) = 8(x + -2) Reorder the terms: -28 + 8x = 8(-2 + x) -28 + 8x = (-2 * 8 + x * 8) -28 + 8x = (-16 + 8x) Add '-8x' to each side of the equation. -28 + 8x + -8x = -16 + 8x + -8x Combine like terms: 8x + -8x = 0 -28 + 0 = -16 + 8x + -8x -28 = -16 + 8x + -8x Combine like terms: 8x + -8x = 0 -28 = -16 + 0 -28 = -16 Solving -28 = -16 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.
