Simplifying 4(2x + -5) = 2x + 6(x + 2) Reorder the terms: 4(-5 + 2x) = 2x + 6(x + 2) (-5 * 4 + 2x * 4) = 2x + 6(x + 2) (-20 + 8x) = 2x + 6(x + 2) Reorder the terms: -20 + 8x = 2x + 6(2 + x) -20 + 8x = 2x + (2 * 6 + x * 6) -20 + 8x = 2x + (12 + 6x) Reorder the terms: -20 + 8x = 12 + 2x + 6x Combine like terms: 2x + 6x = 8x -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.
