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

( me with these problems all is appreciated)
