You can put this solution on YOUR website! Carl is 6 years older than tom. Six years ago carl was 3 times as old as tom. How old are they now
-----
Equations:
c = t + 6
c-6 = 3(t-6)
-------
Substitute for "c" and solve for "t":
t+6-6 = 3(t-6)
t = 3t-18
2t = 18
tom's age is 9
----
carl's age is 9+6 = 15
