11 students in a room shook hands with each other how many handshackes would ther be altogether

34 + y  = 97

Step-by-step explanation:

According to the question,

Total number of sport cards = 97

In which some are foot ball cards and some are non football cards.

Let y be the number of sports cards.

Given, 34 cards are football cards.

Therefore, total number of cards = 34 + y

⇒ 34 + y = 97

Which is the equation that will use to find the number of non football cards.
