Simplifying 2(x + 1) = 2(x + 7) Reorder the terms: 2(1 + x) = 2(x + 7) (1 * 2 + x * 2) = 2(x + 7) (2 + 2x) = 2(x + 7) Reorder the terms: 2 + 2x = 2(7 + x) 2 + 2x = (7 * 2 + x * 2) 2 + 2x = (14 + 2x) Add '-2x' to each side of the equation. 2 + 2x + -2x = 14 + 2x + -2x Combine like terms: 2x + -2x = 0 2 + 0 = 14 + 2x + -2x 2 = 14 + 2x + -2x Combine like terms: 2x + -2x = 0 2 = 14 + 0 2 = 14 Solving 2 = 14 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.
