1) ( 2 1/10 - х) : 8 = 1 1/3 +1 2/15
    (2 1/10 -х) :8 =3 5/15 + 2/15
    (2 1/10 -х) : 8 = 3 7/15
    2 1/10 - х = 3 7/158
    2 1/10 - х = 52/158/1
    2 1/10 - х = 416/15
    - х = 416/15 - 2 1/10 = 27 11/15 - 2 1/10  25 22/30 - 3/30 = 25  19/30
х = - 25 19/30
2) 25/6: (1/4 х - 1 4/15) = 2/3 +1 5/6
     25/6 :(1/4 х -1 4/15) = 1 9/6 = 2  1/2
      1/4 х - 1 4/15 = 25/6: 3/2 = 25/6 2/3 = 25/9  = 2 7/9
       1/4 х = 2 7/9  - 1 4/15 = 1 + 35/45 - 12/45= 1 23/45
       х = 68/45: 1/4 = 68/454/1 = 272/45 = 2 2/45
3) 2 х = 5/3
    х = 5/3: 2/1 = 5/31/2 = 5/6
4) 3 8/10 х - 1 7/10 = 3 1/2
    2 1/10 х = 3 1/2
    21/10 х = 7/2
     х = 7/2: 21/10 = 7/210/21 = 5/3
5)  8/12 х -   3/12 х = 5 1/12 + 7/12 + 5/6
    5/12 х = 5 18/12 = 6 6/12 = 6 1/2
   х = 6 1/2 : 5/12= 13/1212/5 = 13/12 = 1 1/12
