Simplifying 8(v + 2) + -4v = 2(2v + 4) + -9 Reorder the terms: 8(2 + v) + -4v = 2(2v + 4) + -9 (2 * 8 + v * 8) + -4v = 2(2v + 4) + -9 (16 + 8v) + -4v = 2(2v + 4) + -9 Combine like terms: 8v + -4v = 4v 16 + 4v = 2(2v + 4) + -9 Reorder the terms: 16 + 4v = 2(4 + 2v) + -9 16 + 4v = (4 * 2 + 2v * 2) + -9 16 + 4v = (8 + 4v) + -9 Reorder the terms: 16 + 4v = 8 + -9 + 4v Combine like terms: 8 + -9 = -1 16 + 4v = -1 + 4v Add '-4v' to each side of the equation. 16 + 4v + -4v = -1 + 4v + -4v Combine like terms: 4v + -4v = 0 16 + 0 = -1 + 4v + -4v 16 = -1 + 4v + -4v Combine like terms: 4v + -4v = 0 16 = -1 + 0 16 = -1 Solving 16 = -1 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.
