Simplifying 5 + 2(n + 1) = 2n Reorder the terms: 5 + 2(1 + n) = 2n 5 + (1 * 2 + n * 2) = 2n 5 + (2 + 2n) = 2n Combine like terms: 5 + 2 = 7 7 + 2n = 2n Add '-2n' to each side of the equation. 7 + 2n + -2n = 2n + -2n Combine like terms: 2n + -2n = 0 7 + 0 = 2n + -2n 7 = 2n + -2n Combine like terms: 2n + -2n = 0 7 = 0 Solving 7 = 0 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.
