fathers age is 5 times the sons age. if the sum of their ages is 60 yearsm what willbe their ages after 5 years.? step by step p
Vlada [557]

Step-by-step explanation:

let father's age be f yr old and son age be s yr old

f = 5s -(1)

f + s = 60 -(2)

sub (1) into (2):

5s + s = 60

6s = 60

s = 10

f = 60 - 10 = 50

in 5 yr time, father age = 50 + 5 = 55

son age = 10 + 5 = 15
