New issue 2075 by smichr: solve fails for eq1=1 + 2*y/b - (e + x)**2/a;
eq3=1 + 2*y/d - (x - e)**2/c
http://code.google.com/p/sympy/issues/detail?id=2075
The system
eq1=1 + 2*y/b - (e + x)**2/a
eq3=1 + 2*y/d - (x - e)**2/c
solve([eq1,eq3],[x,y])
fails with
raise CoercionFailed("can't convert %s of type %s to %s" % (a, K0, K1))
CoercionFailed: can't convert DMF(([[[-1]]], [[[1]], [[]]]), ZZ) of type
ZZ(a,b,e) to ZZ(a,b,c,d,e)
in master and polys11.
After re-arrangement it succeeds
eq1=b + 2*y - a*(e + x)**2
eq3=d + 2*y - c*(x - e)**2
