5. 3x-X-7=3 6.3x-3-X=3 7. -1 - 2x +3x=5 8. 3x - 22 - X=6 9. 2x+3x-10=10

** 3x - x -7 = 3

2x = 10

x = 5

** 6. 3x - 3 -x = 3

18x - 3 - x = 3

17x = 6

x = $\frac{6}{17}$

** 7. -1 - 2x + 3x = 5

-7 - 2x + 3x = 5

-7 + x = 5

x = 12

** 8. 3x - 22 - x = 6

24x - 22 - x = 6

23x = 28

x = $\frac{28}{23}$

** 9. 2x + 3x -10 = 10

18x + 3x - 10 = 10

21x = 20

x = $\frac{20}{21}$
