Simplifying 3v + 21 = 3(v + 1) Reorder the terms: 21 + 3v = 3(v + 1) Reorder the terms: 21 + 3v = 3(1 + v) 21 + 3v = (1 * 3 + v * 3) 21 + 3v = (3 + 3v) Add '-3v' to each side of the equation. 21 + 3v + -3v = 3 + 3v + -3v Combine like terms: 3v + -3v = 0 21 + 0 = 3 + 3v + -3v 21 = 3 + 3v + -3v Combine like terms: 3v + -3v = 0 21 = 3 + 0 21 = 3 Solving 21 = 3 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.
