Clinic Billing Analysis and Matrix Solutions

An administrative assistant at a local community healthcare clinic is reconciling billing records for patient visits, diagnostic lab tests, and prescriptions. They model the total costs using a system of linear equations. To find the individual unit costs of each service, the assistant decides to solve this system manually using the matrix method.

Describe the complete, systematic step-by-step process the assistant must recall and follow to solve a system of linear equations using matrices. In your essay, explain how to set up the matrix, the specific sequence of row operations required to simplify the matrix, and how to obtain and verify the final solution once the matrix is simplified.
