Step-by-Step Application of Cramer's Rule in Resource Modeling

A business supervisor is preparing a training guide to show how to solve linear systems in production scheduling. The supervisor needs to document the step-by-step application of Cramer's Rule to solve the system of equations representing the production constraints:

{2x+y=43x2y=6\left\{\begin{array}{l} 2x + y = -4 3x - 2y = -6 \end{array}\right.

To help the supervisor, write an essay explaining how to solve this system using Cramer's Rule based on the standard procedure. In your response, make sure to:

  1. Define and evaluate the main determinant DD using the coefficients of the variables.
  2. Define and evaluate the numerator determinant DxD_x by replacing the xx-coefficients with the constants.
  3. Define and evaluate the numerator determinant DyD_y by replacing the yy-coefficients with the constants.
  4. State the formulas for xx and yy, and compute their values.
  5. Explain how to check and verify the final solution in the original equations.
