Fill in the Blank

An inventory auditor is evaluating whether the stock adjustment triple (4,3,4)(-4, -3, 4) satisfies the system constraint xy+z=2x - y + z = 2. Upon substituting x=4x = -4, y=3y = -3, and z=4z = 4 into the left side of the equation, the expression simplifies to ____. Since this value does not equal 2, the triple is immediately rejected as a valid solution.
