We will give solution to the following problem:

"Ishaan is 8 years younger than Daniel. Daniel and Ishaan first met four years ago. Five years ago, Daniel was 3 times as old as Ishaan. How old is Daniel now? How old is Ishaan now?"

Let

x = Ishaan's current age

x + 8 = Daniel's current age

Five years ago, Daniel was 3 times as old as Ishaan:

x + 8 - 5 = 3(x - 5)

........

........

x = 9 years

x + 8 = 9 + 8 = 17 years

Ishaan is 9 years old now.

Daniel is 17 years old now.
