Define variables and write a system of equations for each situation. Solve using substitution.
Suppose you are thinking about buying one of two cars. Car A will cost $17,655. Youn can expect to pay an average of $1230 per year for fuel, maintenance, and repairs. Car B will cost about $15,900. Fuel, maintenance, and repairs for it will average about $1425 per year. After how many years are the total costs for the cars the same?

From your wording,
17,655 + 1230X = 15,900 + 1425X
Solve for X.
I hope this helps. Thanks for asking.
