Помогите решить плес

1)
2x - 4 = x - 3
2x - x = -3 + 4
x = 1
-----------------
2)
-3x - 12 = 6x - 3
6x + 3x = -12 +3
9x = -9
x= -9:9
x = -1
-------------
3)
2x + 3 = -5x - 14
2x + 5x = -14 - 3
7x = -17
x = -17 : 7
x = -2 3/7
----------------
4)
9x + 12 = 4 + x
9x - x = 4 - 12
8x = -8
x = -8 : 8
x = -1
--------------
5)
10x - 4 - 3x - 4 = -8x + 1 + 12x + 20
7x - 8 = 4x + 21
7x - 4x = 21 + 8
3x = 29
x = 29 : 3
x = 9 2/3
