To evaluate the expression \( \frac{5x - 4y}{2} \) when \( x = 8 \) and \( y = 4 \):

1. Substitute \( x = 8 \) and \( y = 4 \) into the expression.

\[
\frac{5(8) - 4(4)}{2}
\]

2. Calculate \( 5(8) \) and \( 4(4) \):

\[
5(8) = 40
\]
\[
4(4) = 16
\]

3. Now substitute those values back into the expression:

\[
\frac{40 - 16}{2}
\]

4. Simplify \( 40 - 16 \):

\[
40 - 16 = 24
\]

5. Now divide by 2:

\[
\frac{24}{2} = 12
\]

Thus, the value of the expression when \( x = 8 \) and \( y = 4 \) is **12**.
