Answer 1

3(x-4)=x+18
3x-12=x+18
2x=30
x=15
Where x is Sanjay's Age

Answer 2

Let the present age of Sanjay be 'x' years.

4 years ago : x - 4

After 18 years : x + 18.

Now,

Given that he will be three times as old as he was 4 years ago after 18 years.

= > 3(x - 4) = x + 18

= > 3x - 12 = x + 18

= > 3x - x = 18 + 12

= > 2x = 30

= > x = 15.

Therefore, the present age of Sanjay is 15 years.

Hope this helps!
