1. **State the problem:** Solve the inequality $$9 + 3(-3t + 10) \leq 6t + 8 - 4$$ for $t$ and write the answer in simplest form.
2. **Apply the distributive property:** Multiply $3$ by each term inside the parentheses:
$$9 + 3 \times (-3t) + 3 \times 10 \leq 6t + 8 - 4$$
which simplifies to
$$9 - 9t + 30 \leq 6t + 8 - 4$$
3. **Combine like terms on the left and right sides:**
$$9 + 30 = 39$$
$$8 - 4 = 4$$
So the inequality becomes
$$39 - 9t \leq 6t + 4$$
4. **Bring all terms involving $t$ to one side and constants to the other:**
Add $9t$ to both sides:
$$39 - \cancel{9t} + 9t \leq 6t + 9t + 4$$
which simplifies to
$$39 \leq 15t + 4$$
Subtract $4$ from both sides:
$$39 - 4 \leq 15t + \cancel{4} - 4$$
which simplifies to
$$35 \leq 15t$$
5. **Isolate $t$ by dividing both sides by 15:**
$$\frac{35}{\cancel{15}} \leq \frac{15t}{\cancel{15}}$$
which simplifies to
$$\frac{35}{15} \leq t$$
6. **Simplify the fraction:**
$$\frac{35}{15} = \frac{7}{3}$$
7. **Write the solution:**
$$t \geq \frac{7}{3}$$
**Note:** The original problem states the answer as $t < $ something, but solving the inequality gives $t \geq \frac{7}{3}$. This is the correct solution based on the inequality given.
**Final answer:**
$$t \geq \frac{7}{3}$$
