x + y = 8 and 1/x + 1/y = 2/3 then product of x and y will be

• any way the sol is as follows
  
  given x+y=8
  and 1/x +1/y =2/3
  
  now (x+y)/xy =2/3
  => 3(x+y)=2xy
  => 3(8)=2xy
  =>xy = 24/2
  => xy =12

• x+y/XY=2/3
  
  xy=12

• x+y/xy=2/3
  xy=8*3/2
  xy=12

• answer is 12....1/x +1/y =(x+y)/(xy)...so xy is 12...

• y=8-x
  1/x+1/(8-x)=2/3
