1. **State the problem:** Find the range of values for which $x+5 < |2x + 1|$.
2. **Understand the absolute value:** The inequality involves an absolute value, so we consider two cases:
- Case 1: $2x + 1 \geq 0$ so $|2x + 1| = 2x + 1$
- Case 2: $2x + 1 < 0$ so $|2x + 1| = -(2x + 1) = -2x - 1$
3. **Case 1: $2x + 1 \geq 0$**
This means $x \geq -\frac{1}{2}$.
The inequality becomes:
$$x + 5 < 2x + 1$$
Subtract $x$ from both sides:
$$5 < x + 1$$
Subtract 1 from both sides:
$$4 < x$$
So for Case 1, the solution is:
$$x > 4$$
But remember $x \geq -\frac{1}{2}$, so the combined condition is:
$$x > 4$$
4. **Case 2: $2x + 1 < 0$**
This means $x < -\frac{1}{2}$.
The inequality becomes:
$$x + 5 < -2x - 1$$
Add $2x$ to both sides:
$$3x + 5 < -1$$
Subtract 5 from both sides:
$$3x < -6$$
Divide both sides by 3:
$$x < -2$$
So for Case 2, the solution is:
$$x < -2$$
Since $x < -\frac{1}{2}$ is already true here, the combined condition is:
$$x < -2$$
5. **Combine both cases:**
The solution to the inequality is:
$$x < -2 \quad \text{or} \quad x > 4$$
**Final answer:** The range of values for which $x+5 < |2x + 1|$ is
$$(-\infty, -2) \cup (4, \infty)$$
