Simplifying 9(v + 1) + -3v = 3(2v + 4) + -15 Reorder the terms: 9(1 + v) + -3v = 3(2v + 4) + -15 (1 * 9 + v * 9) + -3v = 3(2v + 4) + -15 (9 + 9v) + -3v = 3(2v + 4) + -15 Combine like terms: 9v + -3v = 6v 9 + 6v = 3(2v + 4) + -15 Reorder the terms: 9 + 6v = 3(4 + 2v) + -15 9 + 6v = (4 * 3 + 2v * 3) + -15 9 + 6v = (12 + 6v) + -15 Reorder the terms: 9 + 6v = 12 + -15 + 6v Combine like terms: 12 + -15 = -3 9 + 6v = -3 + 6v Add '-6v' to each side of the equation. 9 + 6v + -6v = -3 + 6v + -6v Combine like terms: 6v + -6v = 0 9 + 0 = -3 + 6v + -6v 9 = -3 + 6v + -6v Combine like terms: 6v + -6v = 0 9 = -3 + 0 9 = -3 Solving 9 = -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.
