1. 9x - 6 = 4x - 36
9x - 4x = -36 + 6
5x = -30
x = -6
2. 7x + 9 = 4x + 30
7x - 4x = 30 - 9
3x = 21
x = 7
3. 15x - 7 = 6x + 20
15x - 6x = 20 + 7
9x = 27
x = 3
4. 10x - 2 = 5x - 42
10x - 5x = -42 + 2
5x = -40
x = -8
5. 14x - 6 = 5x - 87
14x - 5x = -87 + 6
9x = -81
x = -9
6. 13x - 6 = 4x + 66
13x - 4x = 66 + 6
9x = 72
x = 8
7. 8x + 3 = 6x + 17
8x - 6x = 17 - 3
2x = 14
x = 7
8. 12x - 6 = 5x - 62
12x - 5x = -62 + 6
7x = -56
x = -8
