An accounting clerk is updating a business ledger with two transactions: subtracting a 7 dollar discount from a 15 dollar balance (${}15 - 7$) and subtracting an 8 dollar expense from a 14 dollar deficit ($-14 - 8$). To simplify these calculations, the clerk applies the subtraction property to rewrite each as the addition of an opposite. Which pair of expressions correctly shows this property being used?

An inventory clerk adjusts stock records in two separate scenarios: removing 7 items from a bin of 15 items (written as ${}15 - 7$) and recording 8 additional damaged items against an existing inventory deficit of 14 items (written as $-14 - 8$). According to the subtraction property, the clerk can rewrite both of these calculations to give the same result by adding the opposite, resulting in the expressions ${}15 + (-7)$ and $-14 + (-8)$.

A payroll clerk is reconciling account discrepancies and needs to simplify several balance adjustments. Match each subtraction operation with its equivalent addition form (using the subtraction property) or its final simplified value.
