Answer 1

Answer:

this language is very disgusting

Answer 2

Answer:

x/y=3/4

4x=3y

x=(3/4)y equation 1

(x-5)/(y-5)=5/7

7(x-5)=5(y-5)

7x-35=5y-25

7x-5y=10 equation 2

put the value of x from equation 1 in equation 2

7(3y/4)-5y=10

21y-20y=40

y=40

put this value of y in equation 1, you will get

x=30
