Пошаговое объяснение:
[tex] \frac{6}{7} (3x - 5) = \frac{3}{14} (x + 2)[/tex]
[tex] \frac{18}{7} x - \frac{30}{7} = \frac{3}{14} x + \frac{6}{14} [/tex]
[tex] \frac{18}{7} x - \frac{3}{14} x = \frac{6}{14 } + \frac{30}{7} [/tex]
подставляем общие число снизу
[tex] \frac{36}{14} x - \frac{3}{14} x = \frac{6}{14} + \frac{60}{14} [/tex]
[tex] \frac{33}{14} x = \frac{66}{14} [/tex]
[tex]x = \frac{66}{14} \div \frac{33}{14} [/tex]
[tex]x = \frac{66}{14} \times \frac{14}{33} [/tex]
[tex]x = 2[/tex]
