If x:y=7:5, then (5x-2y):(3x+2y)= ?

• 25/31 ans.
  sol:-
  x=7y/5
  so putting the value of x we get:
  {5*5y}/{(21+10)*y}=25/31=25:31 ans.

• 25:31
  
  (5x-2y)/(3x+2y)
  x= y*7/5
  
  putting bthis value , we get
  (5x-2y)/(3x+2y) = 25/31

• x:y=7:5 therefore x=7,y=5
  (5x-2y):(3x+2y)=(5*7-2*5):(3*7+2*5)
  =(35-10):(21+10)
  =25:31

• 39 : 31
  (5x-2y)/(3x+2y)
  x= y*7/5
  when we will put this value.
  we will get (49y-10y/5)/(21y+10y/5)=39:31 (Ans)

• assume x=7 y=5 ans rest u all know
  ans=25:31

• x:y=7:5
  x/y=7/5
  5x-2y/3x+2y=5(x/y)-2/3(x/y)+2
  5(7/5)-2/3(7/5)+2
  =25/31
