A budget analyst is verifying if the proposed resource allocation $(4, -1, -5)$ is a solution to the following system of cost equations:

$\left\{\begin{array}{l} 3x + y + z = 2 \\ x + 2y + z = -3 \\ 3x + y + 2z = 4 \end{array}\right.$

The analyst substitutes the values into the first equation, ${} 3x + y + z = 2$, and finds that the expression evaluates to 6, resulting in the false statement ${} 6 = 2$. Based on the definition of a solution for a system of equations, what is the correct conclusion?

A production supervisor is testing whether the resource allocation $(4, -1, -5)$ satisfies a system of three budget equations. After substituting the values into the first equation, ${} 3x + y + z = 2$, the supervisor finds that the left side evaluates to 6. True or False: Because the result 6 does not match the target value of 2, the supervisor can immediately conclude that $(4, -1, -5)$ is not a solution to the system.

A project manager is verifying if the resource allocation $(4, -1, -5)$ satisfies the first constraint of a production model: ${} 3x + y + z = 2$. After substituting the values $x = 4$, $y = -1$, and $z = -5$ into the equation, the left side simplifies to the value ____.

A logistics coordinator is verifying whether a proposed resource distribution plan $(4, -1, -5)$ satisfies the primary constraint of a warehouse model: ${} 3x + y + z = 2$. Arrange the following steps in the correct order to perform this verification process.
