2 \frac{1}{3} = \frac{7}{3}2 \frac{5}{12} = \frac{29}{12}3 \frac{2}{9} = \frac{29}{9}1 \frac{3}{4} = \frac{7}{4}\frac{7}{3}x + \frac{29}{12} = \frac{29}{9}x + \frac{7}{4}x в одну сторону, а числовые значения — в другую: \frac{7}{3}x - \frac{29}{9}x = \frac{7}{4} - \frac{29}{12}\frac{21}{9}x - \frac{29}{9}x = \frac{21}{12} - \frac{29}{12}-\frac{8}{9}x = -\frac{8}{12}-\frac{8}{9}x = -\frac{2}{3}-\frac{8}{9}: x = \frac{-2/3}{-8/9} x = \frac{2}{3} \times \frac{9}{8}x = \frac{18}{24}x = \frac{3}{4}Ответ: x = \frac{3}{4}
