Answer 1

Ответ:

$9 \frac{11}{18} x$

Объяснение:

$3x - 1 \frac{5}{6} x + 8 \frac{4}{9} x = 2\frac{6}{6} x - 1 \frac{5}{6} x + 8 \frac{4}{9} x = 1 \frac{1}{6} x + 8 \frac{4}{9} x = \frac{7}{6} x + \frac{76}{9} x = \frac{3*7}{3*6} x + \frac{2*76}{2*9} x = \frac{21}{18} x + \frac{152}{18} x = \frac{21+152}{18} x = \frac{173}{18} x = 9 \frac{11}{18} x$
