Recalling the Verification Process for System Constraints

A supply chain manager is training a new coordinator on how to verify if proposed material distribution plans meet all manufacturing constraints. The constraints are modeled by the following system of linear equations:

Equation 1: 3x+y+z=2{}3x + y + z = 2 Equation 2: x+2y+z=3x + 2y + z = -3 Equation 3: 3x+y+2z=4{}3x + y + 2z = 4

The coordinator is given two proposed plans: Plan A, represented by the ordered triple (1,3,2)(1, -3, 2), and Plan B, represented by the ordered triple (4,1,5)(4, -1, -5). Based on your knowledge of checking solutions to systems of equations, describe the exact step-by-step mathematical procedure the coordinator must recall and follow to determine if each plan is a valid solution. In your explanation, clearly state the core rule for what ultimately qualifies an ordered triple as a solution to an entire system.
