Simplifying 8(x + 2) + 4 = 8x + 9 Reorder the terms: 8(2 + x) + 4 = 8x + 9 (2 * 8 + x * 8) + 4 = 8x + 9 (16 + 8x) + 4 = 8x + 9 Reorder the terms: 16 + 4 + 8x = 8x + 9 Combine like terms: 16 + 4 = 20 20 + 8x = 8x + 9 Reorder the terms: 20 + 8x = 9 + 8x Add '-8x' to each side of the equation. 20 + 8x + -8x = 9 + 8x + -8x Combine like terms: 8x + -8x = 0 20 + 0 = 9 + 8x + -8x 20 = 9 + 8x + -8x Combine like terms: 8x + -8x = 0 20 = 9 + 0 20 = 9 Solving 20 = 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.
