\[
\begin{aligned}
-5 - (-8) &= 3 \\
2 - (-7) &= 9 \\
\end{aligned}
\]
Solution
Let's solve each subtraction problem step by step.
### 1. \(-5 - (-8)\)
When subtracting a negative number, it's the same as adding the positive counterpart.
\[
-5 - (-8) = -5 + 8
\]
Now, add \(-5\) and \(8\):
\[
-5 + 8 = 3
\]
**Answer:** \(-5 - (-8) = 3\)
---
### 2. \(2 - (-7)\)
Similarly, subtracting a negative number is equivalent to adding its positive form.
\[
2 - (-7) = 2 + 7
\]
Now, add \(2\) and \(7\):
\[
2 + 7 = 9
\]
**Answer:** \(2 - (-7) = 9\)
---
### Summary
\[
\begin{aligned}
-5 - (-8) &= 3 \\
2 - (-7) &= 9 \\
\end{aligned}
\]
