Solution

The problem can be solved by setting up two equations based on the information given:

  1. F + S = 45 (The sum of the father's age and the son's age is 45)
  2. F = S + 35 (The father is 35 years older than the son)

We can substitute equation 2 into equation 1:

(S + 35) + S = 45 2S + 35 = 45 2S = 45 - 35 2S = 10 S = 10 / 2 S = 5

So, the son is 5 years old.
