Simplifying 13(v + 3) + -4v = 3(3v + 2) + -12 Reorder the terms: 13(3 + v) + -4v = 3(3v + 2) + -12 (3 * 13 + v * 13) + -4v = 3(3v + 2) + -12 (39 + 13v) + -4v = 3(3v + 2) + -12 Combine like terms: 13v + -4v = 9v 39 + 9v = 3(3v + 2) + -12 Reorder the terms: 39 + 9v = 3(2 + 3v) + -12 39 + 9v = (2 * 3 + 3v * 3) + -12 39 + 9v = (6 + 9v) + -12 Reorder the terms: 39 + 9v = 6 + -12 + 9v Combine like terms: 6 + -12 = -6 39 + 9v = -6 + 9v Add '-9v' to each side of the equation. 39 + 9v + -9v = -6 + 9v + -9v Combine like terms: 9v + -9v = 0 39 + 0 = -6 + 9v + -9v 39 = -6 + 9v + -9v Combine like terms: 9v + -9v = 0 39 = -6 + 0 39 = -6 Solving 39 = -6 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.
