You should report this on the sympy list. It is mirrored on
news.gmane.org as gmane,comp.python.sympy.
Code:
import csv as csv
import os
import numpy as np
import sympy as sy
#from sympy import solve, Poly, Eq, Function, exp
from sympy import *
from numpy import *
from numpy.linalg import *
from sympy.polys.polyfuncs import interpolate
from sympy import Function, dsolve, Eq, Derivative, sin, cos
from sympy.abc import x
f = sy.Function('f')
x = sy.Symbol("x")
t = sy.Symbol("t")
print(sy.solve([x^2+x+1-t, x^3+x^2-t], x))
print(sy.solve((x^2+x+1-t, x^3+x^2-t), x))
