Simplifying 8(x + -1) + 7 = 6x + 2(-2 + x) Reorder the terms: 8(-1 + x) + 7 = 6x + 2(-2 + x) (-1 * 8 + x * 8) + 7 = 6x + 2(-2 + x) (-8 + 8x) + 7 = 6x + 2(-2 + x) Reorder the terms: -8 + 7 + 8x = 6x + 2(-2 + x) Combine like terms: -8 + 7 = -1 -1 + 8x = 6x + 2(-2 + x) -1 + 8x = 6x + (-2 * 2 + x * 2) -1 + 8x = 6x + (-4 + 2x) Reorder the terms: -1 + 8x = -4 + 6x + 2x Combine like terms: 6x + 2x = 8x -1 + 8x = -4 + 8x Add '-8x' to each side of the equation. -1 + 8x + -8x = -4 + 8x + -8x Combine like terms: 8x + -8x = 0 -1 + 0 = -4 + 8x + -8x -1 = -4 + 8x + -8x Combine like terms: 8x + -8x = 0 -1 = -4 + 0 -1 = -4 Solving -1 = -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.
