Simplifying -3(x + 15) = -1(3x + 15) Reorder the terms: -3(15 + x) = -1(3x + 15) (15 * -3 + x * -3) = -1(3x + 15) (-45 + -3x) = -1(3x + 15) Reorder the terms: -45 + -3x = -1(15 + 3x) -45 + -3x = (15 * -1 + 3x * -1) -45 + -3x = (-15 + -3x) Add '3x' to each side of the equation. -45 + -3x + 3x = -15 + -3x + 3x Combine like terms: -3x + 3x = 0 -45 + 0 = -15 + -3x + 3x -45 = -15 + -3x + 3x Combine like terms: -3x + 3x = 0 -45 = -15 + 0 -45 = -15 Solving -45 = -15 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.
