Simplifying 3(r + 1) + -5 = 3r + -3 Reorder the terms: 3(1 + r) + -5 = 3r + -3 (1 * 3 + r * 3) + -5 = 3r + -3 (3 + 3r) + -5 = 3r + -3 Reorder the terms: 3 + -5 + 3r = 3r + -3 Combine like terms: 3 + -5 = -2 -2 + 3r = 3r + -3 Reorder the terms: -2 + 3r = -3 + 3r Add '-3r' to each side of the equation. -2 + 3r + -3r = -3 + 3r + -3r Combine like terms: 3r + -3r = 0 -2 + 0 = -3 + 3r + -3r -2 = -3 + 3r + -3r Combine like terms: 3r + -3r = 0 -2 = -3 + 0 -2 = -3 Solving -2 = -3 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.
