Age Problem: Alice and Bob

Alice is three times as old as Bob. In 5 years, Alice will be 2 years older than twice Bob's age. How old is Bob now?

Let Alice's age be represented by the variable $A$, and Bob's age by the variable $B$. This gives us two equations:

1. $A = 3B$

2. $A + 5 = 2(B + 5) + 2$
