Given :

Ben's age x is 3 times his age 12 years ago.

To Find :

The  current age of Ben.

Solution :

It is given that current age of Ben is x.

So, his age 12 years ago is (x - 12).

Expressing given condition mathematically , we get :

[tex]x=3(x-12)\\\\x=3x-36\\\\2x=36\\\\x=18\ years[/tex]

Therefore, current age of Ben is 18 years.

Hence, this is the required solution.
