1. **State the problem:** Solve the inequality $$-\left|x-\frac{1}{4}\right| \ge 2 - \frac{1}{2}x$$.
2. **Rewrite the inequality:** Multiply both sides by -1 to remove the negative sign in front of the absolute value. Remember, multiplying an inequality by a negative number reverses the inequality sign.
$$-\left|x-\frac{1}{4}\right| \ge 2 - \frac{1}{2}x \implies \left|x-\frac{1}{4}\right| \le -2 + \frac{1}{2}x$$
3. **Analyze the right side:** The right side is $$-2 + \frac{1}{2}x$$. For the inequality $$\left|x-\frac{1}{4}\right| \le -2 + \frac{1}{2}x$$ to hold, the right side must be non-negative because absolute values are always $$\geq 0$$.
So, set:
$$-2 + \frac{1}{2}x \ge 0$$
Multiply both sides by 2:
$$-4 + x \ge 0$$
$$x \ge 4$$
4. **Rewrite the inequality for $$x \ge 4$$:**
$$\left|x-\frac{1}{4}\right| \le -2 + \frac{1}{2}x$$
5. **Solve the absolute value inequality:**
Recall that $$|A| \le B$$ means $$-B \le A \le B$$ when $$B \ge 0$$.
So,
$$-\left(-2 + \frac{1}{2}x\right) \le x - \frac{1}{4} \le -2 + \frac{1}{2}x$$
Simplify the left inequality:
$$2 - \frac{1}{2}x \le x - \frac{1}{4}$$
Add $$\frac{1}{2}x$$ to both sides:
$$2 \le x - \frac{1}{4} + \frac{1}{2}x$$
Combine like terms:
$$2 \le \frac{3}{2}x - \frac{1}{4}$$
Add $$\frac{1}{4}$$ to both sides:
$$2 + \frac{1}{4} \le \frac{3}{2}x$$
$$\frac{9}{4} \le \frac{3}{2}x$$
Divide both sides by $$\frac{3}{2}$$:
$$\frac{9}{4} \times \frac{2}{3} \le x$$
$$\frac{18}{12} \le x$$
$$\frac{3}{2} \le x$$
6. **Simplify the right inequality:**
$$x - \frac{1}{4} \le -2 + \frac{1}{2}x$$
Subtract $$\frac{1}{2}x$$ from both sides:
$$x - \frac{1}{2}x - \frac{1}{4} \le -2$$
$$\frac{1}{2}x - \frac{1}{4} \le -2$$
Add $$\frac{1}{4}$$ to both sides:
$$\frac{1}{2}x \le -2 + \frac{1}{4}$$
$$\frac{1}{2}x \le -\frac{7}{4}$$
Multiply both sides by 2:
$$x \le -\frac{7}{2}$$
7. **Combine the inequalities:**
From step 3, $$x \ge 4$$.
From step 5, $$x \ge \frac{3}{2}$$.
From step 6, $$x \le -\frac{7}{2}$$.
The right inequality $$x \le -\frac{7}{2}$$ contradicts $$x \ge 4$$, so no $$x$$ satisfies both.
Therefore, the solution must satisfy $$x \ge 4$$ and $$x \ge \frac{3}{2}$$, which simplifies to $$x \ge 4$$.
8. **Check the domain:** Since the right side must be non-negative, $$x \ge 4$$.
**Final solution:**
$$\boxed{x \ge 4}$$
