Answer 1

1) 1/2

5/6х - 1/3 = 1/8 + 1/4

1/2

5/6х - 1/3 = 3/8

$\frac{5}{6} x - \frac{1}{3} = \frac{1}{2} \div \frac{3}{8 }$

$\frac{5}{6} x - \frac{1}{3} = 1 \frac{1}{3}$

$\frac{5}{6} x = \frac{1}{3} + \frac{4}{3}$

$\frac{5}{6} x = 1 \frac{2}{3}$

$x = \frac{5}{3} \div \frac{5}{6}$

х = 2

2). 2/3

2/9+1/3х = 13/14 - 1/2

2/3

2/9+1/3х = 3/7

$\frac{2}{9} + \frac{1}{3} x = \frac{2}{3} \div \frac{3}{7}$

$\frac{2}{9} + \frac{1}{3} x =1 \frac{5}{9}$

$\frac{1}{3} x = \frac{14}{9} - \frac{2}{9}$

$\frac{1}{3} x = 1 \frac{1}{3}$

$x = \frac{4}{3} \div \frac{1}{3}$

х = 4
