Answer 1

А) 6х -12=4х -8
6х -4х =12-8
2х =4
х =4÷2
х =2

б )2/3х =18
х = 18 ÷ 2/3
х = 27

в)(2х -5)- (3х -7)=4
2х -5-3х+7=4
2х -3х=4-7+5
-х= 2
х=-2

г)5 (х-1,2)- 3х = 2
5х - 6 - 3х =2
5х -3х =2+6
2х =8
х = 8÷2
х =4

Answer 2

А) 6x - 12 = 4x - 8
6x - 4x = -8 + 12
2x = 4
x = 2
б) 2/3x = 18
x = 18 : 2/3
x = 18 × 3/2
x = 24/2
x = 12
в) (2x - 5) - (3x - 7) = 4
2x - 5 - 3x + 7 = 4
-x + 2 = 4
-x = 4 - 2
-x = 2
x = -2
г) 5(x - 1,2) - 3x = 2
5x - 6 - 3x = 2
2x - 6 = 2
2x = 2 + 6
2x = 8
x = 4
