1. **State the problem:** Solve the compound inequality $$5 \geq \frac{3n - 2}{2} \geq -10$$ and graph the solution.
2. **Understand the inequality:** This means $$\frac{3n - 2}{2}$$ is between $$-10$$ and $$5$$ inclusive.
3. **Break into two inequalities:**
$$5 \geq \frac{3n - 2}{2}$$ and $$\frac{3n - 2}{2} \geq -10$$
4. **Solve the first inequality:**
Multiply both sides by 2 (positive, so inequality signs stay the same):
$$5 \times 2 \geq \cancel{2} \times \frac{3n - 2}{\cancel{2}}$$
$$10 \geq 3n - 2$$
Add 2 to both sides:
$$10 + 2 \geq 3n$$
$$12 \geq 3n$$
Divide both sides by 3:
$$\frac{12}{\cancel{3}} \geq \frac{3n}{\cancel{3}}$$
$$4 \geq n$$
5. **Solve the second inequality:**
Multiply both sides by 2:
$$\cancel{2} \times \frac{3n - 2}{\cancel{2}} \geq -10 \times 2$$
$$3n - 2 \geq -20$$
Add 2 to both sides:
$$3n \geq -20 + 2$$
$$3n \geq -18$$
Divide both sides by 3:
$$\frac{3n}{\cancel{3}} \geq \frac{-18}{\cancel{3}}$$
$$n \geq -6$$
6. **Combine the results:**
$$-6 \leq n \leq 4$$
7. **Interpretation:** The solution is all values of $$n$$ between $$-6$$ and $$4$$ inclusive.
8. **Graphing:** On a number line from $$-10$$ to $$4$$, mark the points $$-6$$ and $$4$$ with closed dots (since the inequalities are inclusive). Shade the region between $$-6$$ and $$4$$.
**Final answer:** $$\boxed{-6 \leq n \leq 4}$$
