To solve for \( z \), you can isolate \( z \) by adding \( 3.8 \) to both sides of the equation:

\[
8.6 = z - 3.8
\]
\[
8.6 + 3.8 = z
\]
\[
z = 12.4
\]

So, \( z = 12.4 \).

Here are 5 related questions to further your understanding:
1. How would you solve \( z - 4.2 = 7.1 \)?
2. What happens if you subtract \( z \) from both sides of the equation \( 8.6 = z - 3.8 \)?
3. Can you solve the equation \( z + 5.6 = 13.2 \)?
4. How do you solve \( z - 2.4 = -5 \)?
5. What is the general approach to solving equations of the form \( z + a = b \)?

**Tip:** Always perform the same operation on both sides of an equation to maintain equality.
