Comment #2 on issue 1637 by mattpap: solve([Eq(x+a*y,1), Eq(x+y+z, 1),
Eq(z+3*x)], x, y, z, a) troubles
http://code.google.com/p/sympy/issues/detail?id=1637
The system is non-linear and has infinite number of solutions. Our solver
currently
supports only zero-dimensional systems, i.e. finite number of solutions. In
commit
f2203d5c9f4ae19ea6cd087cd858bf04554dbc1f in polys8 branch I changed the
error message
to something more meaningful and the exception to NotImplementedError.
The result in #1 is obviously wrong. The problem was with Poly.is_linear
and was
fixed in commit d96b7a6edf4a669a8576ab2be9384e7100b4141d.
