Billing System Reconciliation

An automated billing system records a transaction where an initial balance (yy) was increased by a service fee of 37, resulting in a final balance of -13. To verify the starting balance, you need to isolate the variable in the equation y+37=13y + 37 = -13. Based on your training, identify the specific mathematical property of equality that must be applied and state the exact value that should be subtracted from both sides.
