Answer 1

Ответ:

$x = 10\frac{1}{2}$

Пошаговое объяснение:

$\frac{7}{18}x - \frac{5}{12} = 3\frac{2}{3}\\\\\frac{7}{18}x - \frac{5}{12} = \frac{11}{3} \\\\\frac{14}{36}x - \frac{15}{36} = \frac{132}{36} \\\\\frac{14}{36}x = \frac{132}{36} + \frac{15}{36}\\\\\frac{14}{36}x = \frac{147}{36}\\\\x = \frac{147}{36} : \frac{14}{36} = \frac{147}{36} * \frac{36}{14} = \frac{147}{14} = 10\frac{7}{14} = 10\frac{1}{2}$
