Reconciling the Store Coin Safe

A retail supervisor is training a new cashier to reconcile a vending machine's coin canister containing nickels and quarters. To solve for the quantities of each coin, they apply a standard seven-step problem-solving strategy using a system of equations. After solving the equations, they must complete Step 6 of the strategy.

What is the specific name of Step 6 in this seven-step strategy, and what two distinct verification checks must the cashier perform in this step to ensure the calculated values for the number of nickels (nn) and quarters (qq) are correct?
