First subtract h from both sides.
10+h-h>2+2h-h
10>2+h
Then subtract 2 from both sides.
10-2>2-2+h
8>h
We can then flip 8>h to h<8 just because it's a more standard way of writing it.
Final answer: h<8

Because you added 14 cards to your collection, we'll have to subtract that:
40 - 14 = 26
Knowing that 26 cards is half of your old card deck, we know that your old card deck is:
26*2 = 52
You have option b. 52 cards before.
