Answer 1

Answer:

Let the number of years after which the father will be three times the age of the son be x.

So according to the question, the equation goes as follows:

45 + x = 3*(5 + x)

45 + x = 15 + 3x

2x = 30

x = 15 years.

Therefore; after 15 years, the father will be three times the age of the son!
