Question 762770
So if it's 5 years ago, the two ages add to 35. 

We can say that x=the son's age. the father is 6x older than the son when their ages add up to 35.

6x+x=35
7x=35
x=5

father is 6(5)=30 son is 5

30-5=25

The father was 25 when the son was born.


Edit: I'm more so here to learn myself, i'm not a tutor. Just looking to sharpen up math by asking and answering questions before school starts.
