To find the solution set for the given inequalities and equations, we'll solve them one by one.
1. **For the inequality \( 2x > -8 \)**:
Divide both sides by 2:
\[
x > -4
\]
So the solution set for this inequality is:
\(\{x | x > -4\}\)
2. **For the equation \( -5x + 7 = 12 \)**:
First, subtract 7 from both sides:
\[
-5x = 12 - 7
\]
\[
-5x = 5
\]
Now, divide both sides by -5 (remember to reverse the inequality because we're dividing by a negative):
\[
x = -1
\]
Now we can summarize the solutions:
- The solution to \(2x > -8\) is \(\{x | x > -4\}\).
- The solution to \(-5x + 7 = 12\) is \(x = -1\).
Thus, the relevant solution sets are:
- \(\{x | x > -4\}\)
- \(\{-1\}\)
Since the question likely asks for a single solution set from the options given, the most relevant solution regarding \(x\) being greater than a certain value is:
**Answer**: \(\{x | x > -4\}\)
