10=-3r+8r Since r is on the right-hand side of the equation, switch the sides so it is on the left-hand side of the equation. -3r+8r=10 Since -3r and 8r are like terms, subtract 8r from -3r to get 5r. 5r=10 Divide each term in the equation by 5. r=2
OpenStudy (anonymous):
Factor your r and then divide by what's in parenthesis |dw:1338860113226:dw|
