1) -4x = 24
x = -24/4
x = -6
2) 6 = x - 3
6 + 3 = x
9 = x
3) 5x - 5 = 20
5x = 20 + 5
5x = 25
x = 25/5
x = 5
4) x + 10 = 18
x = 18 - 10
x = 8
5) 6x = 12
x = 12/6
x = 2
6) - 1 + 5x = 49
5x = 49 + 1
5x = 50
x = 50/5
x = 10
7) 10 + 7x = 24
7x = 24 - 10
7x = 14
x = 14/7
x = 2
8) 3x - 1 - x = 15
3x - x = 15 + 1
2x = 16
x = 16/2
x = 8
9) 66 = 3x + 4x - 4
66 + 4 = 3x + 4x
70 = 7x
70/7 = x
10 = x
10) 6x + 5 - 4x = 21
6x - 4x = 21 - 5
2x = 16
x = 16/2
x = 8
11) -2 - 6x - 2x = 86
- 6x - 2x = 86 + 2
-8x = 88
x = -88/8
x = -11
12) -2x + 1 = -17
-2x = -17 + 1
-2x = -16
x = -16/-2
x = 16/2
x = 8
