a midsize car with a 4-cylinder engine goes 34 miles on a gallon of gasoline. This is 10 miles more than a luxury car with an 8 cylinder engine goes on a gallon of gasoline. How many miles does a luxury car travel on a gallon of gasoline?

There's a bunch of information here that doesn't matter. Sometimes the secret to a story problem is figuring out what can be ignored :-)

oh okay but what would it be when you write an equation for this problem?

Midsize car's mileage per gallon = x. That's 10 miles more than a luxury car goes. Luxury car goes midsize mileage - 10. Luxury car mileage = x - 10.

All that stuff about the number of cylinders is just there to confuse you :-)
