Verification Procedures in Elimination

In a professional setting, mathematical solutions must be documented and verified before they are used in production models. For the system of equations {4x - 3y = 9, 7x + 2y = -6}, describe the specific numerical 'Check' process (Step 7) used in the elimination method. Your response should detail how the solution (0, -3) is substituted into both original equations and state the resulting numerical identities that confirm the answer's accuracy.
