x'=xy(adsbygoogle = window.adsbygoogle || []).push({});

y'=4x+y

solver these both

the first equation can be seprated and end up with ln|x|=(y^2)/2 but then if you solve for y and try to plug into the second equation you get somethin ugly:

y'=4x+sqrt(2ln|x|)

or if you try to find roots you get somethin even uglier y"=4e^(y^2/2)+y

im at a lose at how to do this, can anyone hlep me.

thanks in advance
