А) 11/х - 2 = 11/2

11/х = 11/2 + 2

11/х = 11/2 + 4/2

11/х = 15/2

11 : 22/15 - 2 = 11/2

11 * 15/22 - 2 = 11/2

1/1 * 15/2 - 2 = 11/2

15/2 - 2 = 11/2

15/2 - 4/2 = 11/2

11/2 = 11/2

б) 7/х + 6 = - 7/6

7/х = - 7/6 - 6

1/1 * (- 43/6) + 6 = - 7/6

- 43/6 + 6 = - 7/6

- 43/6 + 36/6 = - 7/6

- 7/6 = - 7/6
