3,4х+1,02:1/5-1/6=2х+0,6:1/10-11
3,4+1,02*5-1,6=2х+0,6*10-11
3,4х+5,1-1,6=2х+6-11
3,4х-2х= -5-3,5
1,4х= - 8,5
х= - 8,5:1,4
х= - 17/2 * 5/7
х= - 85/14= - 6 1/14

15/22-(4-1 5/6) :х=1 5/33
15/22-2 1/ 6х=1 5/33
13/6х=15/22-1 5/33
13/6х=45/66-1 10/66= - 31/66
-31/66 *6х=13
-31/11 х=13
х= -  13 :31/11
х= - 13*11/31
х= - 143/31 = - 4 19/31
