" 9."(x+y)/(xy)=2;(x-y)/(xy)=6

Solve: (x+y)/(xy)=2 and (x-y)/(xy)=6

(xy)/(x+y)=6/5 ; (xy)/(y-x)=6

Solve the following system of equations by method of cross-multiplication: (x+y)/(xy)=2,quad (x-y)/(xy)=6

Solve the following system of equations: (x+y)/(xy)=2,quad (x-y)/(xy)=6

The value of y when (x+y)/(xy)=2" and "(x-y)/(xy)=6 is

(xy)/(x+y)=(6)/(5)(xy)/(y-x)=6

Solve the simultaneous equations : (6x+3y)/(xy) = 6, (2x+4y)/(xy) = 5

If x,y,z are real numbers such that xy=6,x-z=2 and x+y+z=9, compute (x)/(y)-(z)/(x)-(z^(2))/(xy)

If x-y= (x+y)/(9)= (xy)/(6) then value of xy= ?
