To find the car's current mileage, we can set up an equation.

Let x be the car's current mileage.

We know that in 4 years, the mileage increases by 12,000 miles each year. So, the total increase in mileage will be: 12,000 miles/year × 4 years.

After 4 years, the car's mileage will be 80,000 miles. So, the current mileage plus the increased mileage equals 80,000 miles.

We can set up the equation:<...
