The expression to solve is \( 8z - 6 \), and we are asked to find its value when \( z = 4 \).

Substitute \( z = 4 \) into the expression:

\[
8(4) - 6 = 32 - 6 = 26
\]

Thus, the value of the expression is \( 26 \).

Would you like further details or have any questions? 

Here are five related questions to consider:
1. What would the expression evaluate to if \( z = 3 \)?
2. How would the value change if the expression was \( 8z + 6 \)?
3. Can you create a similar expression and solve for a different value of \( z \)?
4. How would you solve if the equation was \( 8z - 6 = 0 \)?
5. What happens if you replace \( z \) with a negative number?

**Tip**: Always substitute values step-by-step to avoid small calculation errors.
