Instead of doing it for you, I'll do one exactly like it step by step.

Janet is three times as old as James . The sum of their ages is 64.
How old are each?

We look at the first sentence:

Janet is three times as old as James.

Let James' age be x 
Then Janet's age is 3 times x or 3x.

We look at the second sentence:

The sum of their ages is 64.

x + 3x = 64
    4x = 64
     x = 16

Therefore James' age = 16
And Janet's age = 3x = 3(16) = 48

Now do yours exactly the same way.
