OpenStudy (shadowfiend):
You can distribute each multiplication in turn to create a final expression that you can solve. For example, 5(6 -r) will be 30 - 5r. Then you have 5(7 - (30 - 5r)), which is 5(7 - 30 + 5r), which is 5(5r - 23). Then you distribute the 5. You can do the same on the other side of the equals and then solve for r the normal way.
