Simplifying 4(5x + 2) = 2(10x + 7) Reorder the terms: 4(2 + 5x) = 2(10x + 7) (2 * 4 + 5x * 4) = 2(10x + 7) (8 + 20x) = 2(10x + 7) Reorder the terms: 8 + 20x = 2(7 + 10x) 8 + 20x = (7 * 2 + 10x * 2) 8 + 20x = (14 + 20x) Add '-20x' to each side of the equation. 8 + 20x + -20x = 14 + 20x + -20x Combine like terms: 20x + -20x = 0 8 + 0 = 14 + 20x + -20x 8 = 14 + 20x + -20x Combine like terms: 20x + -20x = 0 8 = 14 + 0 8 = 14 Solving 8 = 14 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.
