Ordinary Simultaneous Differential Equation

Please help me to solve this Ordinary Simultaneous Differential Equation:

$\frac{dx}{x^2}=\frac{dy}{y^2}=\frac{dz}{nxy}$

I got first solution : $x-y=c_1xy$

But didn't get second one.. Please help me..

Thanks in advance..

Solve what you have for $y$ and substitute into

$\dfrac{dx}{x^2} = \dfrac{dz}{nxy}$

separate and integrate.
