4. Реши уравнение:$$\frac{1\frac{1}{3}}{6x-4} = \frac{0.6}{3x-4}$$.

$$\frac{1\frac{1}{3}}{6x-4} = \frac{0.6}{3x-4}$$

$$\frac{\frac{4}{3}}{6x-4} = \frac{\frac{3}{5}}{3x-4}$$

$$\frac{4}{3(6x-4)} = \frac{3}{5(3x-4)}$$

$$\frac{4}{18x-12} = \frac{3}{15x-20}$$

$$4(15x-20) = 3(18x-12)$$

$$60x - 80 = 54x - 36$$

$$6x = 44$$

$$x = \frac{44}{6}$$

$$x = \frac{22}{3}$$

$$x = 7\frac{1}{3}$$

Ответ: $$x = 7\frac{1}{3}$$.
