To solve the absolute value inequality \( |2x + 3| > 4 \), we can break it down into two cases:
1. \( 2x + 3 > 4 \)
2. \( 2x + 3 < -4 \)
**Case 1: \( 2x + 3 > 4 \)**
Subtract 3 from both sides:
\[
2x > 1
\]
Now divide by 2:
\[
x > \frac{1}{2}
\]
**Case 2: \( 2x + 3 < -4 \)**
Subtract 3 from both sides:
\[
2x < -7
\]
Now divide by 2:
\[
x < -\frac{7}{2}
\]
Combining both cases, we have the solution:
\[
x < -\frac{7}{2} \quad \text{or} \quad x > \frac{1}{2}
\]
Therefore, the correct response from the provided options is:
**x < -7/2 or x > 1/2**
1. \( 2x + 3 > 4 \)
2. \( 2x + 3 < -4 \)
**Case 1: \( 2x + 3 > 4 \)**
Subtract 3 from both sides:
\[
2x > 1
\]
Now divide by 2:
\[
x > \frac{1}{2}
\]
**Case 2: \( 2x + 3 < -4 \)**
Subtract 3 from both sides:
\[
2x < -7
\]
Now divide by 2:
\[
x < -\frac{7}{2}
\]
Combining both cases, we have the solution:
\[
x < -\frac{7}{2} \quad \text{or} \quad x > \frac{1}{2}
\]
Therefore, the correct response from the provided options is:
**x < -7/2 or x > 1/2**
