Answer 1

$5 frac{1}{2} x + 3 frac{5}{6} = 7 frac{3}{4} x + 2 frac{2}{3} \ 3frac{5}{6} - 2 frac{2}{3} = 7 frac{3}{4} x - 5 frac{1}{2} x \ 3frac{5}{6} - 2 frac{4}{6} = 7 frac{3}{4} x - 5 frac{2}{4} x \ 1 frac{1}{6} = 2 frac{1}{4} x \ x = 1 frac{1}{6} div 2 frac{1}{4} \ x = frac{7 times 4}{6 times 9} \ x = frac{7 times 2}{3 times 9} \ x = frac{14}{27}$
