Simplifying 8x + -2x + -12 = 4(x + 1) + 2x Reorder the terms: -12 + 8x + -2x = 4(x + 1) + 2x Combine like terms: 8x + -2x = 6x -12 + 6x = 4(x + 1) + 2x Reorder the terms: -12 + 6x = 4(1 + x) + 2x -12 + 6x = (1 * 4 + x * 4) + 2x -12 + 6x = (4 + 4x) + 2x Combine like terms: 4x + 2x = 6x -12 + 6x = 4 + 6x Add '-6x' to each side of the equation. -12 + 6x + -6x = 4 + 6x + -6x Combine like terms: 6x + -6x = 0 -12 + 0 = 4 + 6x + -6x -12 = 4 + 6x + -6x Combine like terms: 6x + -6x = 0 -12 = 4 + 0 -12 = 4 Solving -12 = 4 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.
