Answer 2

2 / (1 3/5х) - 1/х = 1/12,

2 / (8/5х) - 1/х = 1/12,

2 / (8/5х) - (8/5)/(8/5х) = 1/12,

(2 - 8/5) / (8/5х) = 1/12,

(10/5 - 8/5) / (8/5х) = 1/12,

(2/5) / (8/5х) = 1/12,

8/5х = 2/5 * 12,

8/5х = 24/5,

х = 24/5 : 8/5,

х = 24/5 * 5/8,

х = 24/8,

х = 3,

проверка:

2 / (1 3/5 * 3) - 1/3 = 1/12,

2 / (24/5) - 1/3 = 1/12,

2 : 24/5 - 1/3 = 1/12,

2 * 5/24 - 1/3 = 1/12,

10/24 - 8/24 = 1/12,

2/24 = 1/12,

1/12 = 1/12
