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