Standard Operating Procedure for Cramer's Rule

An office manager is updating the team's training manual for resource planning. To ensure all coordinators can find solutions to inventory constraints, the manager needs to write a clear, step-by-step guide on how to solve a system of two linear equations in two variables (xx and yy) using Cramer's Rule. Describe the standard six-step procedure the manager should document, explaining how to evaluate each determinant (DD, DxD_x, and DyD_y), how to compute the variables, how to present the final answer, and how to verify that the solution is correct.
