In SymPy 0.7.6.1 I'm getting:
Python 3.5.1 |Continuum Analytics, Inc.| (default, Dec 7 2015, 11:16:01)
Type "copyright", "credits" or "license" for more information.
IPython 4.0.1 -- An enhanced Interactive Python.

In [1]: from sympy import *
In [2]: from sympy.abc import x
In [3]: Eq(x+1, 4)
Out[3]: x + 1 == 4
Which is correct. What versions of SymPy are you using?
