A car company tested new tires. The test drive was (5x - 1) miles on a flat road, (4x2 - 9) miles uphill, and (9x) miles downhill. What expression would represent the total distance that the car was test?

I'm struggling a lot on being able to answer this, any help is appreciated!

You would want to solve for X X=miles
the x you are using is it to use as times something or as a variable?
