An environmental technician is monitoring air quality sensors represented by the variables $x$, $y$, and $z$. The sensors are considered synchronized if their readings satisfy the following system of linear equations:

$\left\{\begin{array}{l} x - y + z = 2 2x - y - z = -6 2x + 2y + z = -3 \end{array}\right.$

Based on the synchronization test for the ordered triple $(-2, -1, 3)$, which of the following statements is true?

A supply chain analyst is checking an inventory allocation model described by the variables $x$, $y$, and $z$. The model is governed by the following system of equations:

$\left\{\begin{array}{l} x - y + z = 2 2x - y - z = -6 2x + 2y + z = -3 \end{array}\right.$

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

A logistics analyst is verifying if the resource allocation triple $(-2, -1, 3)$ is a valid solution for the system of optimization equations shown below. To ensure the verification is performed correctly, arrange the following steps of the protocol in their proper chronological order.

$\left\{\begin{array}{l} x - y + z = 2 2x - y - z = -6 2x + 2y + z = -3 \end{array}\right.$

A quality control technician is verifying whether the machine setting triple $(-2, -1, 3)$ is a solution for a system of efficiency constraints. Match each linear expression from the system below with the specific numerical result obtained when the variables are substituted with $x = -2$, $y = -1$, and $z = 3$.

$\left\{\begin{array}{l} x - y + z = 2 2x - y - z = -6 2x + 2y + z = -3 \end{array}\right.$

Verifying Manufacturing Process Adjustments

Verifying Production Targets with Ordered Triples

An operations assistant at a distribution center is validating a storage coordination system represented by three variables: $x$, $y$, and $z$. To check whether the specific warehouse adjustment setting $(-2, -1, 3)$ is a valid solution, the assistant must verify that it satisfies each system constraint. The first constraint equation is $x - y + z = 2$. When the assistant substitutes the values $x = -2$, $y = -1$, and $z = 3$ into the left side of this equation, they get the expression $-2 - (-1) + 3$. When simplified, this expression evaluates to the numerical value of ____, which matches the right side of the first equation.
