To solve the absolute value equation \(|2x + 1| = 5\), we need to consider the two cases that arise from the definition of absolute value.
### Case 1:
\[
2x + 1 = 5
\]
Subtracting 1 from both sides:
\[
2x = 4
\]
Dividing by 2:
\[
x = 2
\]
### Case 2:
\[
2x + 1 = -5
\]
Subtracting 1 from both sides:
\[
2x = -6
\]
Dividing by 2:
\[
x = -3
\]
Thus, the solutions to the equation \(|2x + 1| = 5\) are:
\[
x = 2 \quad \text{and} \quad x = -3
\]
The correct response is:
**x=2, −3**
