Simplifying 5r + -3 = 5(r + -3) Reorder the terms: -3 + 5r = 5(r + -3) Reorder the terms: -3 + 5r = 5(-3 + r) -3 + 5r = (-3 * 5 + r * 5) -3 + 5r = (-15 + 5r) Add '-5r' to each side of the equation. -3 + 5r + -5r = -15 + 5r + -5r Combine like terms: 5r + -5r = 0 -3 + 0 = -15 + 5r + -5r -3 = -15 + 5r + -5r Combine like terms: 5r + -5r = 0 -3 = -15 + 0 -3 = -15 Solving -3 = -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.
