5/x-3=-6/13
Решите пропорцию пожалуйста!

5/х - 3 = - 6/13

5/х = - 6/13 + 3

5/х = 2 7/13

5/х = 33/13

33х = 5 * 13

х = 65/33

х = 1 32/33

Проверка: 5 : 65/33 - 3 = - 6/13

                  5 * 33/65 - 3 = - 6/13

                  165/65 - 3 = - 6/13

                  2 35/65 - 3 = - 6/13

                  2 7/13 - 3 = - 6/13

                  - 6/13 = - 6/13
