20 children share some cards equally. When another child joins them, they each get 2 fewer cards. How many cards are they sharing altogether?

My answer:

children = ch

cards = cd

=> cd/ch

but when another child joins them, they get 2 fewer cards. So, ch = cds - 2.

then I did cd/20(cds - 2)

Then I got stuck there for a long time.
