Simplifying 8r + -3 = 4(2r + 5) Reorder the terms: -3 + 8r = 4(2r + 5) Reorder the terms: -3 + 8r = 4(5 + 2r) -3 + 8r = (5 * 4 + 2r * 4) -3 + 8r = (20 + 8r) Add '-8r' to each side of the equation. -3 + 8r + -8r = 20 + 8r + -8r Combine like terms: 8r + -8r = 0 -3 + 0 = 20 + 8r + -8r -3 = 20 + 8r + -8r Combine like terms: 8r + -8r = 0 -3 = 20 + 0 -3 = 20 Solving -3 = 20 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.
