# Math Help - Ordinary Simultaneous Differential Equation

1. ## 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..

2. Solve what you have for $y$ and substitute into

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

separate and integrate.

3. Thank You very much for giving me such a useful hint.....

4. So you don't need any more help?
