Answer 2

Answer:

Sum of sons' present ages = 15

Man's present age = 45

Step-by-step explanation:

Sum of sons' present ages = x

Man's present age = y

Sum of sons' ages after 5 years = x + 5 + 5 = x + 10

Man's age after 5 years = y + 5

y = 3x                 ---------> (1)

y + 5 = 2(x + 10) ---------> (2)

Substituting 1 in 2,

3x + 5 = 2x + 20

3x - 2x = 20 - 5

x = 15

y = 45

Hope this helps! :)
