Answer 1

$(7 \frac{5}{6} - 3 \frac{4}{12} )x = \frac{4}{9} \\ ( \frac{47}{6} - \frac{40}{12} )x = \frac{4}{9} \\ \frac{9}{2} x = \frac{4}{9} \\ x = \frac{8}{81}$

$(9 \frac{1}{3} + 2 \frac{6}{7} )x = \frac{6}{7} \\ ((9 + 2) + ( \frac{1}{3} + \frac{6}{7} ))x = \frac{6}{7} \\ (11 + \frac{25}{21} )x = \frac{6}{7} \\ (11 + 1 \frac{4}{21} )x = \frac{6}{7} \\ 12 \frac{4}{21} x = \frac{6}{7} \\ \frac{256}{21} x = \frac{6}{7} \\ x = \frac{9}{128}$
