Answer 2

Hey dude here is your Answer------------------------ ✔️❣️❣️❣️❣️

Given the ages of x and y 3:5

Let the ages will be 3x and 5x

According to the problem......

=> (3x - 9):(5x-9)=3:4 .......

=> 4(3x-9)=3(5x-9)

=> 12x-36= 15x - 27

=> 12x - 15x = -27+36

=> - 3x = 9

=> - x = 9/3

=> - x = 3

=> x = - 3

* The ages of y is -12 years....
