Answer 1

To evaluate the expression \( 9 + \frac{n}{3} - 6 \) when \( n = 12 \), we first substitute \( n \) with 12:

\[
9 + \frac{12}{3} - 6
\]

Next, we calculate \( \frac{12}{3} \):

\[
\frac{12}{3} = 4
\]

Now we can substitute this back into the expression:

\[
9 + 4 - 6
\]

Now, we perform the addition and subtraction:

\[
9 + 4 = 13
\]

Then subtract 6:

\[
13 - 6 = 7
\]

Thus, the value of the expression is

\(\boxed{7}\).
