what method would be the best if i want to solve more than one ordinary differentials equations? or how would i attack this kind of problem? for example:

Question

dy/dt = (1-y)/(1+x+y)
dx/dt = (y-x)/[2(1+x+y)]
i just need a starting point cause i couldn't think of a way~ :P
any help would be appreciated~ :)

Answer 1

The system cannot be solved.
