(b+6) - 4 = 10 equals b = 8.
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.
