N is a placeholder for a number. In this case, it is 4
We will replace every copy of 'n' with '4' and then simplify
So n+8 turns into 4+8 which simplifies to 12
Is 12 less than or equal to 13? Yes it is. Specifically it is less than 13. So n = 4 is part of the solution set.
Here is how you'd write it all out using algebra
![n+8 \le 13](https://tex.z-dn.net/?f=n%2B8%20%5Cle%2013)
![4+8 \le 13](https://tex.z-dn.net/?f=4%2B8%20%5Cle%2013)
![12 \le 13](https://tex.z-dn.net/?f=12%20%5Cle%2013)
The last inequality is true so the first inequality is true when n = 4. This is another way to see that n = 4 is a solution.
