Simplifying 20x + 81 = 4(5x + 22) Reorder the terms: 81 + 20x = 4(5x + 22) Reorder the terms: 81 + 20x = 4(22 + 5x) 81 + 20x = (22 * 4 + 5x * 4) 81 + 20x = (88 + 20x) Add '-20x' to each side of the equation. 81 + 20x + -20x = 88 + 20x + -20x Combine like terms: 20x + -20x = 0 81 + 0 = 88 + 20x + -20x 81 = 88 + 20x + -20x Combine like terms: 20x + -20x = 0 81 = 88 + 0 81 = 88 Solving 81 = 88 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.
