6 face cards in a deck minus the red ones so it would be [6-3=3]
52 cards are in a deck and you have 3 black face card so it would be [3/52=0.0576]
Then to get your percentage it would be [0.0576 x 100=5.76%]
5.76 rounded up is 6%

So first, you want to open the parenthesis here.
So, to do that, first look at the symbol before the parenthesis.
In this case it's a -.
So when it's a -, reverse the symbol inside the parenthesis. (This is because if you don't you're subtracting 2x and then adding 8, when really you're subtracting both 2x and 8.)
So,
9x - 2x - 8
Or simplified,
7x - 8
