1. 2x - 12 = 6
2. 2x + 6= 8
3. 12s - 12=12
4. 14s + 6 = 35
5. 3s - 12 = 6
6. 18t + 9 = 34
7. 21x + 7 = 28
8. 50y + 5 = 105
9. 1/4x - 6 = 24
10. 13x + 2 = 18
11. 6 - 3x = 18
12. 14 + s = 21
13. 16x - 4 = 28
14. 19x - 1 + 3 = 40
15. 10t = 194
16. 400x + 100 = 1100
17. 40 - 3x + 3 = 113
(Please help me with these problems all is appreciated)
