This is not homework, these equations are constraints I've encountered in some GR work.(adsbygoogle = window.adsbygoogle || []).push({});

But I'm hopeless with differential equations and I have two I need to solve. Even after reading some instructive texts, I still can't do it.

[tex]\frac{dB(x)}{dx} = \frac{B(x)}{x} - \frac{1}{x}[/tex]

[tex]\frac{dB(x)}{dx} = \frac{B(x)}{x} - \frac{1}{x} + \frac{K}{B(x)}[/tex]

K is a constant. I know the first one has a solution but the second one might not.
