((4x+3y) + (5x+9y)/(5x+5y))= ? is(x/2y) = 2

• the solution is :
  
  (4x + 3y + 5x + 9y)/(5x + 5y) - (1)
  
  as x/2y =2 .. so put x = 4y in eq (1)
  
  so we get [4(4y) + 3y + 5(4y) + 9y]/(5(4y)+5y)
  
  = y(16+3+20+9)/y(25)
  
  therefore, ans is 48/25 (sorry for the mistake)

• put x=4y
  or
  divide by y in both deno. nd nume. then put x/y=4

• (4x+3y+5x+9y)/(5x+5y)
  on subs x=4y(given),get
  48/25

• solution is:
  substitute x=4y in the above equation
  
  =[4(4y) + 3y + 5(4y) + 9y]/(5(4y)+5y)
  =y(16+3+20+9)/y(25)
  = 48/25 -ans

• 9x+12y/5x+5y=2;
  9x+9y=10x+10y;
  x=2y;
  ?=2
