Solving by Elimination
To solve the system by elimination, first eliminate the variable . Adding the first and second equations together yields the two-variable equation . Adding the second and third equations together generates another two-variable equation, . This forms a new sub-system: . Adding these two new equations firmly eliminates both remaining variables, resulting in the mathematically false statement . Because the process leaves a definitively false statement, the system is strictly inconsistent and has no valid solution.

As a logistics analyst, you are creating a standard operating procedure (SOP) to manually verify automated supply chain optimizations that involve three interdependent variables (like transport, storage, and labor costs). Arrange the steps for solving a system of three linear equations using the elimination method in the correct procedural order for your team's training manual.
A financial analyst is solving a system of three linear equations to determine the optimal investment distribution across three funds: Growth (), Income (), and Stability (). After successfully combining the first and second equations to eliminate the variable, what is the next mandatory step in the elimination procedure to reduce the system to two variables?
A logistics coordinator is documenting the standard operating procedure (SOP) for manually calculating material distribution across three separate job sites using systems of linear equations. Match each procedural milestone with its correct technical description in the elimination method.
Initial Procedural Step in System Elimination
According to the systematic seven-step procedure for solving a system of three linear equations, the final step is to verify the solution by checking that the calculated ordered triple satisfies all three of the original equations.

Your supply chain team is balancing three different departmental budget allocations, with the constraints modeled by the following system of equations:
To find a valid budget distribution, you begin by eliminating the variable . You add the first and second equations together, and then you add the second and third equations together to form a new two-variable sub-system. When you add the two equations of this new sub-system together to eliminate the remaining variables, what specific mathematical statement do you recall resulting from this process?
