Explanation

When son was born, father's age = son's current age. Let son's current age = S. Then father is 2S years old (S years at son's birth + S years since). Given 2S = 46, so S = 23. Son's age 7 years back = 23 - 7 = 16 years. The key insight is that the age difference equals the son's current age.
