Let's go through both problems one by one:

### 8) Find the sum or difference:
\[
(-3.71) - (-8.43)
\]
Subtracting a negative number is equivalent to adding, so:
\[
(-3.71) - (-8.43) = -3.71 + 8.43
\]
Now, calculate:
\[
8.43 - 3.71 = 4.72
\]
So, the correct answer is **4.72**.

### 9) Find the sum or difference:
\[
6.58 - 9.51
\]
Subtracting a larger number from a smaller one will give a negative result:
\[
6.58 - 9.51 = -2.93
\]
So, the correct answer is **-2.93**.
