A logistics manager is comparing two different fuel consumption models for a fleet of delivery trucks. To find the point where the models predict identical fuel usage, the manager sets up a system of linear equations. After performing algebraic substitution, the variables are completely eliminated, leaving the final statement ${}0 = 15$. What does this result prove about the fuel consumption models?

A project manager is comparing two different resource allocation models using a system of linear equations to find a point of equilibrium. If the algebraic solving process results in the elimination of all variables and leaves a false statement such as ${}0 = 120$, it is correct to conclude that the system is inconsistent and has no solution.

A financial analyst is comparing two different investment growth models using a system of linear equations to determine if they will ever yield the same return. While solving the system algebraically, the analyst finds that all variables are completely eliminated, leaving only the false mathematical statement ${}0 = 25$. Based on this result, the analyst concludes that the system of equations is ____.

Interpreting Algebraic Contradictions in Cost Analysis

An inventory manager is evaluating two different storage cost models by solving a system of linear equations. Arrange the chronological steps in the correct order to recall how the manager algebraically identifies that the system is an inconsistent system.
