Simplifying 8(x + -2) + 15 = 2x + 3(2x + 5) Reorder the terms: 8(-2 + x) + 15 = 2x + 3(2x + 5) (-2 * 8 + x * 8) + 15 = 2x + 3(2x + 5) (-16 + 8x) + 15 = 2x + 3(2x + 5) Reorder the terms: -16 + 15 + 8x = 2x + 3(2x + 5) Combine like terms: -16 + 15 = -1 -1 + 8x = 2x + 3(2x + 5) Reorder the terms: -1 + 8x = 2x + 3(5 + 2x) -1 + 8x = 2x + (5 * 3 + 2x * 3) -1 + 8x = 2x + (15 + 6x) Reorder the terms: -1 + 8x = 15 + 2x + 6x Combine like terms: 2x + 6x = 8x -1 + 8x = 15 + 8x Add '-8x' to each side of the equation. -1 + 8x + -8x = 15 + 8x + -8x Combine like terms: 8x + -8x = 0 -1 + 0 = 15 + 8x + -8x -1 = 15 + 8x + -8x Combine like terms: 8x + -8x = 0 -1 = 15 + 0 -1 = 15 Solving -1 = 15 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.
