To solve the equation \( n + 7 = 20 \), follow these steps:

1. **Isolate the variable \( n \):**
   Subtract 7 from both sides of the equation:
   \[
   n + 7 - 7 = 20 - 7
   \]

2. **Simplify:**
   \[
   n = 13
   \]

So, the solution is \( n = 13 \).

Would you like more details, or do you have any questions? Here are five related questions to consider:

1. What if the equation was \( n - 7 = 20 \)?
2. How can you check if the solution \( n = 13 \) is correct?
3. How would the solution change if the equation were \( n + 7 = 25 \)?
4. What if the equation included a negative constant, like \( n + 7 = -20 \)?
5. Can you solve an equation with a different variable on both sides, like \( n + 7 = m + 2 \)?

**Tip:** Always perform the same operation on both sides of an equation to maintain equality.
