Simplifying 8(x + 5) + 9 = 8x + 9 Reorder the terms: 8(5 + x) + 9 = 8x + 9 (5 * 8 + x * 8) + 9 = 8x + 9 (40 + 8x) + 9 = 8x + 9 Reorder the terms: 40 + 9 + 8x = 8x + 9 Combine like terms: 40 + 9 = 49 49 + 8x = 8x + 9 Reorder the terms: 49 + 8x = 9 + 8x Add '-8x' to each side of the equation. 49 + 8x + -8x = 9 + 8x + -8x Combine like terms: 8x + -8x = 0 49 + 0 = 9 + 8x + -8x 49 = 9 + 8x + -8x Combine like terms: 8x + -8x = 0 49 = 9 + 0 49 = 9 Solving 49 = 9 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.
