Ben is 3 times as old as Daniel and is also 4 years older than Daniel.

Let Ben's age be b, let Daniel's age by d. We're given:

1. b = 3d
2. b = d + 4

Substitute (1) into (2)
3d = d + 4

Type this equation into our search engine, and we get d = 2.

Substitute this into equation (1), and we get:
b = 3(2)
b = 6

So Daniel is 2 years old and Ben is 6 years old.
