Answer:

syd is 23 and dev is 69


Step-by-step explanation:

Let Dev's age be x and Syd's age be y

Since Dev is 3 times older than Syd, we may write  

x

=

3

y

Since the sum of their ages is 92, we may write  

x

+

y

=

92

Now replacing x with 3y, we get :  

3

y

+

y

=

92

Hence  

y

=

92

4

=

23

and so Syd is 23 year old.

Back substituting we get Dev is 69 years old.
