Simplifying 2(5x + -15) = 10(x + -15) Reorder the terms: 2(-15 + 5x) = 10(x + -15) (-15 * 2 + 5x * 2) = 10(x + -15) (-30 + 10x) = 10(x + -15) Reorder the terms: -30 + 10x = 10(-15 + x) -30 + 10x = (-15 * 10 + x * 10) -30 + 10x = (-150 + 10x) Add '-10x' to each side of the equation. -30 + 10x + -10x = -150 + 10x + -10x Combine like terms: 10x + -10x = 0 -30 + 0 = -150 + 10x + -10x -30 = -150 + 10x + -10x Combine like terms: 10x + -10x = 0 -30 = -150 + 0 -30 = -150 Solving -30 = -150 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.
