To solve the equation \( n - 7 = 12 \), you need to isolate the variable \( n \).

Here’s the step-by-step solution:

1. **Add 7 to both sides** of the equation to isolate \( n \):
   \[
   n - 7 + 7 = 12 + 7
   \]
   Simplifying this, you get:
   \[
   n = 19
   \]

So, the value of \( n \) is \( 19 \).
