1. 3x + 5x + 14x = 22x
2. 4x + 7 + 11x = 15x+7
3. 10x + 8 - 3x= 7x+8
4. 6x - 5 + X - 11 = 7x-16
5. -8x + 19 + 2 - 2x = -10x+21
6. X + 23 + 4x - 34 - X = 4x-11
7. 105 + 27x - 68 - 19x - 27 + x = 9x +10
8. 7x + 16 - 3x + 3 - 2x - 2x = 19
9. -18 + 6 - 4x + 10 - 11x + 2 = -15x
10. 16 + 4x - 12x - 28 - 6x + 17 + x - 1 = -13x+4
