This question is very simple
First the question tells us that Bob three years ago was twice as old as Adam
So we have b-3 (b representing Bob). The question then says let "a" represent Adam's age.
So:
b-3=2(a+4)<--(this equation a+4 is because "a" represents Adam's age and 4 because 4 years from now)
Now simplify:
b-3=2a+8
b=2a+11
2a+11 is your answer
