Answer 2

let common multiply ratio be x and y

according to first condition
5 x + 9y = 0 ...................(1)
according to second condition
3x + 5y = 5 ...............(2)
Now,
multiply equation 1 by 5
and 2 by 9
we get 5(5x +9 y = 0)
25 x + 45 y = 5 ...............(3)

9(3x +5y =5)
27x +45y=45 .........(4)
from 3 and 4
25x + 45 y = 5
- 27x +45y=45
:x = 20

we put value in eq
2
y = 20
x = 35
i hope it's help you
