Yan had 5 cards and received \( t \) more from his friend, totaling 16 cards. This can be shown with the addition equation:
\[
5 + t = 16
\]
To find out how many cards his friend gave him, use the subtraction equation:
\[
16 - 5 = t
\]
Solución
1. **Addition Equation**
Yan starts with 5 cards and his friend adds \( t \) cards. After the addition, Yan has 16 cards. This can be modeled as:
\[
5 + t = 16
\]
2. **Subtraction Equation**
To find out how many cards his friend added, we subtract the 5 cards Yan originally had from the total of 16 cards:
\[
16 - 5 = t
\]

The addition equation representing the situation is \( 5 + t = 16 \), which shows that Yan started with 5 cards and his friend gave him \( t \) cards, resulting in a total of 16 cards. The corresponding subtraction equation is \( 16 - 5 = t \), illustrating that if you take away the 5 cards Yan had originally from the total he now has, you will find out how many cards his friend gave him.
