To find the number of sports books \( n \) that Elizabeth reads, we can set up the following equation based on the information given:
\[
n + 10 = 23
\]
Here:
- \( n \) represents the number of sports books.
- 10 is the number of mystery books she reads.
- 23 is the total number of books she reads.
Now, we can solve for \( n \):
1. Start with the equation:
\[
n + 10 = 23
\]
2. Subtract 10 from both sides:
\[
n = 23 - 10
\]
3. Simplify:
\[
n = 13
\]
Thus, Elizabeth reads **13 sports books**.
\[
n + 10 = 23
\]
