Answer 1

Пошаговое объяснение:

в)

$2\frac{1}{6}-(x+1\frac{1}{12} ) = 4\frac{3}{4}\\\frac{13}{6}-(x+\frac{13}{12} ) = \frac{19}{4}\\\frac{13}{6}-x-\frac{13}{12} = \frac{19}{4}\\-x = \frac{19}{4} - \frac{13}{6} + \frac{13}{12}\\-x = \frac{11}{3}\\x = - \frac{11}{3}$

г)

$4\frac{3}{4}-(x+2\frac{3}{8} ) = 1\frac{1}{6}\\\frac{19}{4}-(x+\frac{19}{8} ) = \frac{7}{6}\\\frac{19}{4}-x-\frac{19}{8} = \frac{7}{6}\\-x = \frac{7}{6} - \frac{19}{4} + \frac{19}{8}\\-x = - \frac{29}{24}\\x = \frac{29}{24}$
