Question: -3x(1-4/3)=
1. **State the problem:** Simplify the expression $$-3x(1-\frac{4}{3})$$.
2. **Recall the distributive property:** When you have a number multiplied by a difference inside parentheses, you can simplify inside the parentheses first, then multiply.
3. **Simplify inside the parentheses:**
$$1 - \frac{4}{3} = \frac{3}{3} - \frac{4}{3} = -\frac{1}{3}$$
4. **Substitute back:**
$$-3x \times \left(-\frac{1}{3}\right)$$
5. **Multiply:**
$$-3x \times -\frac{1}{3} = \cancel{-3}x \times \cancel{-\frac{1}{3}} = x$$
6. **Final answer:**
$$x$$
