Simplifying 5 + 2(n + 2) = 2n Reorder the terms: 5 + 2(2 + n) = 2n 5 + (2 * 2 + n * 2) = 2n 5 + (4 + 2n) = 2n Combine like terms: 5 + 4 = 9 9 + 2n = 2n Add '-2n' to each side of the equation. 9 + 2n + -2n = 2n + -2n Combine like terms: 2n + -2n = 0 9 + 0 = 2n + -2n 9 = 2n + -2n Combine like terms: 2n + -2n = 0 9 = 0 Solving 9 = 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.
