Given that \( q = 5 \), you can substitute this value into the expression \( 2 + q \).

\[
2 + q = 2 + 5 = 7
\]

So, the result is \( 7 \).

Would you like more details or have any other questions?

### Relative Questions:
1. How would you solve for \( q \) if the expression were \( q - 2 = 5 \)?
2. What if \( q \) was a negative number? How would the expression change?
3. How can you express the sum \( 2 + q \) in terms of a different variable, like \( p = q + 3 \)?
4. What if you have multiple variables, such as \( 2 + q + r = 10 \)? How would you solve it?
5. How does the expression change if you multiply the entire equation \( 2 + q \) by a constant, like \( 3 \)?

### Tip:
When substituting values into algebraic expressions, ensure all variables are replaced correctly to avoid errors in calculations.
