Simplifying 2(x + 4) + 4 = 2x + 5 Reorder the terms: 2(4 + x) + 4 = 2x + 5 (4 * 2 + x * 2) + 4 = 2x + 5 (8 + 2x) + 4 = 2x + 5 Reorder the terms: 8 + 4 + 2x = 2x + 5 Combine like terms: 8 + 4 = 12 12 + 2x = 2x + 5 Reorder the terms: 12 + 2x = 5 + 2x Add '-2x' to each side of the equation. 12 + 2x + -2x = 5 + 2x + -2x Combine like terms: 2x + -2x = 0 12 + 0 = 5 + 2x + -2x 12 = 5 + 2x + -2x Combine like terms: 2x + -2x = 0 12 = 5 + 0 12 = 5 Solving 12 = 5 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.
