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