1. **State the problem:** Solve the inequality $$-7x - \left(-5x + \frac{1}{4}\right) \leq -1$$.
2. **Apply the distributive property:** Remove the parentheses by distributing the minus sign:
$$-7x + 5x - \frac{1}{4} \leq -1$$.
3. **Combine like terms:**
$$(-7x + 5x) - \frac{1}{4} \leq -1$$
$$-2x - \frac{1}{4} \leq -1$$.
4. **Isolate the variable term:** Add $\frac{1}{4}$ to both sides:
$$-2x - \frac{1}{4} + \frac{1}{4} \leq -1 + \frac{1}{4}$$
$$-2x \leq -\frac{3}{4}$$.
5. **Divide both sides by $-2$ to solve for $x$:** Remember, dividing by a negative number reverses the inequality sign:
$$x \geq \frac{-\frac{3}{4}}{-2}$$
$$x \geq \frac{3}{4} \times \frac{1}{2}$$
$$x \geq \frac{3}{8}$$.
**Final answer:**
$$x \geq \frac{3}{8}$$.
This means $x$ can be any number greater than or equal to $\frac{3}{8}$.
