Recall of System Solution Definition in Resource Allocation

An operations analyst is verifying whether a proposed resource distribution plan represented by the ordered triple (4,−1,−5)(4, -1, -5) satisfies a system of three linear budget constraints:

{3x+y+z=2x+2y+z=−33x+y+2z=4\left\{\begin{array}{l} 3x + y + z = 2 x + 2y + z = -3 3x + y + 2z = 4 \end{array}\right.

After substituting the plan's values into the first constraint equation, 3x+y+z=2{}3x + y + z = 2, the analyst finds that the expression evaluates to 6, resulting in the false mathematical statement 6=2{}6 = 2.

Recall the formal definition of a solution to a system of linear equations. Based on this definition, write a brief essay explaining why evaluating a single equation to a false statement is mathematically sufficient to conclude that (4,−1,−5)(4, -1, -5) is not a solution to the entire system.
