Question

A father is 25 yrs older than his daughter.in 3 yrs the father's age will be 5 yrs more than twice tht of the daughter.find their present age.

Answer 1

Answer:

father =42

daughter =17

Step-by-step explanation:

father = x

daughter= y

x - 25 = y

(x+3) -5 = 2 (y+3)

x -2 = 2y +6

x - 8 = 2y

we have 2 eq

1. x-25=y

2. x-8=2y

eleminate ,eq 1 - eq 2

-17 = -y

y = 17

daughter age = 17

substitute y=17 in eq 2

x-8 =2(17)

x= 42

father age =42
