Answer 1

Пошаговое объяснение:

1/3х - 2 = 1/4х + 1

1/3х - 1/4х = 1 + 2

4/12х - 3/12х = 3

1/12х = 3

х = 3 : 1/12

х = 3 * 12/1

х = 36/1

х = 36

1/6х - 8 = -5/6х + 10

1/6х + 5/6х = 10 + 8

6/6х = 18

х = 18

2/7х - 1/7х = 2

1/7х = 2

х = 2 : 1/7

х = 2 * 7/1

х = 14/1

х = 14

-4/5х - 2/3 = 1/5х + 1/3

-4/5х - 1/5х = 1/3 + 2/3

-5/5х = 3/3

-х = 1

х = -1
