Simplifying 7(3n + 2) = 21n + 2 Reorder the terms: 7(2 + 3n) = 21n + 2 (2 * 7 + 3n * 7) = 21n + 2 (14 + 21n) = 21n + 2 Reorder the terms: 14 + 21n = 2 + 21n Add '-21n' to each side of the equation. 14 + 21n + -21n = 2 + 21n + -21n Combine like terms: 21n + -21n = 0 14 + 0 = 2 + 21n + -21n 14 = 2 + 21n + -21n Combine like terms: 21n + -21n = 0 14 = 2 + 0 14 = 2 Solving 14 = 2 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.
