1) 1/2

5/6х - 1/3 = 1/8 + 1/4

1/2

5/6х - 1/3 = 3/8

[tex] \frac{5}{6} x - \frac{1}{3} = \frac{1}{2} \div \frac{3}{8 } [/tex]

[tex]\frac{5}{6} x - \frac{1}{3} = 1 \frac{1}{3} [/tex]

[tex]\frac{5}{6} x = \frac{1}{3} + \frac{4}{3}[/tex]

[tex] \frac{5}{6} x = 1 \frac{2}{3} [/tex]

[tex]x = \frac{5}{3} \div \frac{5}{6} [/tex]

х = 2

2). 2/3

2/9+1/3х = 13/14 - 1/2

2/3

2/9+1/3х = 3/7

[tex] \frac{2}{9} + \frac{1}{3} x = \frac{2}{3} \div \frac{3}{7} [/tex]

[tex]\frac{2}{9} + \frac{1}{3} x =1 \frac{5}{9} [/tex]

[tex] \frac{1}{3} x = \frac{14}{9} - \frac{2}{9} [/tex]

[tex] \frac{1}{3} x = 1 \frac{1}{3}[/tex]

[tex]x = \frac{4}{3} \div \frac{1}{3} [/tex]

х = 4
