(1) 6x - 12 = 3x
6x - 3x = 12
3x = 12
x = 12 : 3 = 4
(2) 7x - 3 = 5x + 7
7x - 5x = 7 + 3
2x = 10
x = 10 : 2 = 5
(3) 5x + 15 = -2x + 1
5x + 2x = 1 - 15
7x = -14
x = -14 : 7 = -2
(4) 3 + 7x = 4x - 6
7x - 4x = -6 - 3
3x = -9
x = -9 : 3 = -3
(5) 8 + 2x = 3x - 1
2x - 3x = -1 - 8
-x = -9
x = 9
(6) 3x + 2 = x + 4
3x - x = 4 - 2
2x = 2
x = 2 :2 = 1
