Simplifying (x + 7) * 2 = 2x + 13 Reorder the terms: (7 + x) * 2 = 2x + 13 Reorder the terms for easier multiplication: 2(7 + x) = 2x + 13 (7 * 2 + x * 2) = 2x + 13 (14 + 2x) = 2x + 13 Reorder the terms: 14 + 2x = 13 + 2x Add '-2x' to each side of the equation. 14 + 2x + -2x = 13 + 2x + -2x Combine like terms: 2x + -2x = 0 14 + 0 = 13 + 2x + -2x 14 = 13 + 2x + -2x Combine like terms: 2x + -2x = 0 14 = 13 + 0 14 = 13 Solving 14 = 13 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.
