1. **State the problem:** Solve the inequality $$\frac{x - 11}{2} > 3x + 5.5$$ for $x$.
2. **Write down the inequality:**
$$\frac{x - 11}{2} > 3x + 5.5$$
3. **Eliminate the fraction by multiplying both sides by 2:**
$$\cancel{2} \times \frac{x - 11}{\cancel{2}} > 2 \times (3x + 5.5)$$
$$x - 11 > 6x + 11$$
4. **Bring all terms involving $x$ to one side and constants to the other:**
$$x - 6x > 11 + 11$$
$$-5x > 22$$
5. **Divide both sides by $-5$ to solve for $x$. Remember, dividing by a negative number reverses the inequality sign:**
$$\frac{-5x}{\cancel{-5}} < \frac{22}{\cancel{-5}}$$
$$x < -\frac{22}{5}$$
6. **Final answer:**
$$x < -\frac{22}{5}$$
This corresponds to option ⓐ.
**Explanation:** When multiplying or dividing an inequality by a negative number, the inequality sign flips. Here, dividing by $-5$ changed $>$ to $<$.
