5. Решите уранение: (-4)-(-1) (2x-8)=0.

Решение:

1. \[(-4) \cdot \left(-\frac{1}{3}\right) \cdot \left(\frac{2x-8}{2}\right) = 0\]
2. \[\frac{4}{3} \cdot \frac{2x-8}{2} = 0\]
3. \[\frac{4(2x-8)}{3 \cdot 2} = 0\]
4. \[4(2x-8) = 0\]
5. \[2x - 8 = 0\]
6. \[2x = 8\]
7. \[x = \frac{8}{2}\]
8. \[x = 4\]

Ответ: x = 4
