1) 8х - 5= х - 408х - х = 5 - 40
7х = - 35
х=-35÷7
х = - 5
Ответ: х = - 7
2) 9 + 13у = 35 + 26у
26у - 13у = 9 - 35
13у = - 26
у = - 26÷13
у = -2
Ответ: у = - 2
3) 6s + (3s - 2) = 14
6s + 3s - 2 = 14
9s - 2 = 14
9s = 14 + 2
9s = 16
s=16÷9
s = 1 целая 7/9
Ответ: s= 1целая 7/9
4) 8у - ( 7у - 142) = 51
8у - 7у +142 = 51
у +142 = 51
у = 51 - 142
у = - 91
Ответ: у = - 91
5)(6х+ 1) - (3 - 2х) = 14
6х + 1 - 3 + 2х = 14
8х - 2 = 14
8х = 14 + 2
8х = 16
х = 16÷8
х = 2
Ответ: х = 2
