\item \self 
Let $x$ and $y$ be two 32-bit vector variables.
Complete the python code with the appropriate variable declarations and constraint statements to check whether the following equivalence holds:

    $$x \lxor y \equiv (((y \land x)*-2) + (y + x))$$

  \begin{pythonSourceCode}
    from z3 import *

    s = Solver()










    print(s.check())

  \end{pythonSourceCode}
