Answer:
The numbers are 15 and 21
Step-by-step explanation:
Let the constant be x
So 5x and 7x
According to the question, (5x-3)/(7x-3) =2/3
So, by cross multiplication,
3*(5x-3) = 2*(7x-3)
15x-9 = 14x-6
x= -6+9
x= 3
So your numbers are 5x=5*3 =15
7x=7*3 =21

Answer:
ratio= 5:7
let let the number to be 5x and 7x
(A.T.Q) => if 3 is subtracted in both number then their ratio will be 2:3
so equation is => 5x-3/7x-3 = 2/3
=> 3(5x-3) = 2(7x-3)
=> 15x-15 = 14x-6
=> 15x-14x= -6+15
=> x = 9
