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)
