Let's solve the compound inequality step by step.
1. **Solve the first part of the inequality:**
\(2x - 2 < -12\)
Add 2 to both sides:
\[
2x < -10
\]
Now, divide by 2:
\[
x < -5
\]
2. **Solve the second part of the inequality:**
\(2x + 3 > 7\)
Subtract 3 from both sides:
\[
2x > 4
\]
Now, divide by 2:
\[
x > 2
\]
3. **Combine the results:**
From the inequalities we have found:
\[
x < -5 \quad \text{or} \quad x > 2
\]
Thus, the solution to the compound inequality is:
\[
x < -5 \quad \text{or} \quad x > 2
\]
### Graphing the solution:
On the number line:
- For \(x < -5\), draw an open circle at -5 and shade to the left.
- For \(x > 2\), draw an open circle at 2 and shade to the right.
### Final answer:
The correct option from your provided choices is:
**\(x < -5 \quad \text{or} \quad x > 2\)**
