True/False

A supply chain analyst is checking an inventory allocation model described by the variables xx, yy, and zz. The model is governed by the following system of equations:

{xy+z=22xyz=62x+2y+z=3\left\{\begin{array}{l} x - y + z = 2 \\ 2x - y - z = -6 \\ 2x + 2y + z = -3 \end{array}\right.

True or False: When the analyst tests the specific allocation (2,1,3)(-2, -1, 3) by substituting x=2x = -2, y=1y = -1, and z=3z = 3 into each equation, all three substitutions result in true mathematical statements, confirming this allocation is a valid solution for the system.
