The expression provided in the image is:

\[
\frac{7a + b}{c}
\]
where:
- \( a = 2 \)
- \( b = 7 \)
- \( c = 6 \)

Now, let's substitute the values of \( a \), \( b \), and \( c \) into the expression:

\[
\frac{7(2) + 7}{6}
\]

First, calculate the numerator:

\[
7(2) + 7 = 14 + 7 = 21
\]

Now, divide the result by \( c = 6 \):

\[
\frac{21}{6} = 3.5
\]

So, the evaluated result is:

\[
3.5
\]

Here are 5 related questions for practice:
1. What is the value of the expression if \( a = 3 \), \( b = 5 \), and \( c = 4 \)?
2. How does changing \( b \) affect the value of the expression?
3. Can you simplify the expression \(\frac{7a + b}{c}\) for general values of \(a\), \(b\), and \(c\)?
4. What happens to the result if \(c = 0\) in the expression?
5. How would you evaluate a similar expression, \(\frac{5a - b}{c}\), with given values?

**Tip**: When working with expressions, always simplify step by step and check for division by zero to avoid undefined values.
