Three quarters of the cars in a parking garage are black, 4/7 of the remaining cars are blue, and the rest are silver. If there are 9 silver cars, how many cars are in the parking garage?

3/4 of the cars are black. 

1/4 of the cars are not black. 

1/4 * 4/7 = 1/7 of the cars are blue

3/28 of the cars are silver. 

3/28x = 9

Solve x.
