Answer 5

First of all make sure you include brackets where needed, otherwise the answer might give totally different meaning.

The requirement is to isolate b from the rest.. so first reduce 3a from both sides then get rid of the coefficient of b (which is 2) by dividing

So now are sure about your answer
