Simplifying 15(2x + 2) = 10(3x + 4) Reorder the terms: 15(2 + 2x) = 10(3x + 4) (2 * 15 + 2x * 15) = 10(3x + 4) (30 + 30x) = 10(3x + 4) Reorder the terms: 30 + 30x = 10(4 + 3x) 30 + 30x = (4 * 10 + 3x * 10) 30 + 30x = (40 + 30x) Add '-30x' to each side of the equation. 30 + 30x + -30x = 40 + 30x + -30x Combine like terms: 30x + -30x = 0 30 + 0 = 40 + 30x + -30x 30 = 40 + 30x + -30x Combine like terms: 30x + -30x = 0 30 = 40 + 0 30 = 40 Solving 30 = 40 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.
