let Cayla's age be C and Jose's age J
if three times Cayla's age plus Jose's age equal 60, we have
3C%2BJ=60.......eq.1
if Cayla's age is three times Jose's age, we have
C=3J.........eq.2, substitute in eq.1

3%2A3J%2BJ=60.......eq.1
9J%2BJ=60
10J=60
J=6
go to
C=3J.........eq.2, substitute J
C=3%2A6
C=18
Cayla is 18 years old

Let x be the Jose age.


Then the Cayla age is 3x.


From the condition, you have this equation


    3*(3x) + x = 60


      9x   + x = 60

         10x   = 60

           x   = 60/10 = 6.


So, Jose is 6 years old;  then Cayla is 3*6 = 18 years old.    ANSWER

Solved.
