1906 - 1)
 1.   19х - 0,18 = 19,01
19х = 19,01 + 0,18 = 19,19
х = 1,01
2. 2,27 - 2х  = 0,09
2х = 2,27-0,09 = 2,18
х = 1,09
3.   5,08 + 12х = 29,74
12х = 29,74 - 5,08 = 24,66
х = 2,055

1906 - 2)
1.  3,2х + 5,6 + 5,8х = 17,21
9х = 11,61
х = 1,29
2.   3х + 1,2х +6,7х = 109
10,9х =  109
х = 10
3,  6,7х + 1,9х +3,3х = 38,08
11,9х = 38,08
х = 3,2
