1. **State the problem:** Simplify the expression $$\frac{2 \left( \frac{4}{2-x} \right) - 4}{x}$$.
2. **Rewrite the numerator:** Multiply inside the parentheses:
$$2 \times \frac{4}{2-x} = \frac{8}{2-x}$$
So the numerator becomes:
$$\frac{8}{2-x} - 4$$
3. **Find a common denominator for the numerator:**
Rewrite 4 as \(\frac{4(2-x)}{2-x}\):
$$\frac{8}{2-x} - \frac{4(2-x)}{2-x} = \frac{8 - 4(2-x)}{2-x}$$
4. **Simplify the numerator inside the fraction:**
$$8 - 4(2-x) = 8 - 8 + 4x = 4x$$
5. **So the numerator is:**
$$\frac{4x}{2-x}$$
6. **Rewrite the entire expression:**
$$\frac{\frac{4x}{2-x}}{x}$$
7. **Divide by \(x\) by multiplying by its reciprocal:**
$$\frac{4x}{2-x} \times \frac{1}{x} = \frac{4x}{2-x} \times \frac{1}{x}$$
8. **Cancel common factors:**
$$\frac{\cancel{4x}}{2-x} \times \frac{1}{\cancel{x}} = \frac{4}{2-x}$$
**Final answer:**
$$\boxed{\frac{4}{2-x}}$$
