Simplifying 2(r + 4) = 2(r + 3) Reorder the terms: 2(4 + r) = 2(r + 3) (4 * 2 + r * 2) = 2(r + 3) (8 + 2r) = 2(r + 3) Reorder the terms: 8 + 2r = 2(3 + r) 8 + 2r = (3 * 2 + r * 2) 8 + 2r = (6 + 2r) Add '-2r' to each side of the equation. 8 + 2r + -2r = 6 + 2r + -2r Combine like terms: 2r + -2r = 0 8 + 0 = 6 + 2r + -2r 8 = 6 + 2r + -2r Combine like terms: 2r + -2r = 0 8 = 6 + 0 8 = 6 Solving 8 = 6 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.
