[" (fii) "(xy)/(x+y)=(1)/(5)],[(xy)/(x-y)=(1)/(9)]

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

Solve for x and y:(xy)/(x+y)=(1)/(5),x+y!=0;(xy)/(x-y)=(1)/(7),x-y!=0

Solve the following simultaneous linear equations in two variables by the method of elimination : (xy)/(x+y)=1/5, (xy)/(x-y)=1/9

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

(xy)/(x-y)=(1)/(2);(xy)/(x+y)=(1)/(5) wherex +y!=0;x-y!=0

Solve for x and y(x+y)/(xy)=1,(x-y)/(xy)=5

(1)/(log_(x)xy)+(1)/(log_(y)xy)

Simplify: (11)/(2)x^(2)y-(9)/(4)xy^(2)+(1)/(4)xy-(1)/(14)y^(2)x+(1)/(15)yx^(2)+(1)/(2)xy

The value of f(x,y)=((x^(3)y)^((1)/(4))-(y^(3)x)^((1)/(4)))/(sqrt(y)-sqrt(x))+(1+sqrt(xy))/((xy)^((1)/(4)))xx((1+2sqrt((y)/(x))+(y)/(x))^(4) when x=9 and y=0.04

When x=5 and y=2 , the expression (xy)/(70)+(9)/(5(x+y))+(1)/(x+y)=?
