10. 3x – x +4 = 4(2x-1) 11. 4(2x +1) = 5x + 3x +9

12. 10+ x = 5 (1/5x + 2)

13. 8 (x + 2) = 2x + 16

14. 3+ 3/2x + 4 = 4x – 5/2x

15. 3/2 (2x +6) = 3x +9

16. ½ (2-4x) +2x = 13

17. 12 + 2x – x = 9x +6

18. 4x +1 = 2 (2x + 3)

19. 4 (x + 3) - 4 = 8(½x + 1)

20. X + 5x + 4 = 3(2x – 1)

21. 5 (x + 2) - 3x = 2 (x +5)
