Answer

Yan had 5 cards and received \( t \) more from his friend, totaling 16 cards. So, the addition equation is \( 5 + t = 16 \), and the subtraction equation is \( 16 - 5 = t \).

Beyond the Answer

To model the problem, we can set up an addition equation and a subtraction equation. The addition equation is \( 5 + t = 16 \), which shows that the 5 cards Yan started with, plus the \( t \) cards his friend gave him, equals 16. For the subtraction equation, we can express it as \( 16 - t = 5 \), indicating that if you take away the \( t \) cards Yan received from the total of 16, you are left with the original 5 cards he had.
