First, simplify brackets. Your problem should look like: b + 6 - 4 = 10. Second, simplify b + 6 - 4 to b + 2. Your problem should look like: b + 2 - 10. Third, subtract 2 from both sides. Your problem should look like: b = 10 - 2. Fourth, simplify 10 - 2 to get 8. Your problem should look like: b = 8, which is the answer.
