Simplifying 19(v + 4) + -3v = 4(4v + 2) + -9 Reorder the terms: 19(4 + v) + -3v = 4(4v + 2) + -9 (4 * 19 + v * 19) + -3v = 4(4v + 2) + -9 (76 + 19v) + -3v = 4(4v + 2) + -9 Combine like terms: 19v + -3v = 16v 76 + 16v = 4(4v + 2) + -9 Reorder the terms: 76 + 16v = 4(2 + 4v) + -9 76 + 16v = (2 * 4 + 4v * 4) + -9 76 + 16v = (8 + 16v) + -9 Reorder the terms: 76 + 16v = 8 + -9 + 16v Combine like terms: 8 + -9 = -1 76 + 16v = -1 + 16v Add '-16v' to each side of the equation. 76 + 16v + -16v = -1 + 16v + -16v Combine like terms: 16v + -16v = 0 76 + 0 = -1 + 16v + -16v 76 = -1 + 16v + -16v Combine like terms: 16v + -16v = 0 76 = -1 + 0 76 = -1 Solving 76 = -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.
