43/9 = 4 7/9.
Next, those last 7 cars still have an extra tire.
There fore, 7 cars have a spare tire.

spare+onaxels (being used)=43
ok, 1 car has 4 tires not including spare
we know that there are 9 cars
and we know that there are 43 tires
therefor we just find out how many wheels are being used currently aka how many are NOT spare
9 cars
4 wheels per car
9 times 4=36
36 are NOT spare
spare+NOT spare=43
spare+36=43
subtract 36 from both sides
spare=7
7 spare tire
some cars may have more than 1 spare tire, but we will assume that the average car has 1 spare tire per car
7 cars
