Question
i just need to check my work- thankyou

31.  Solve:  
    -6 ≤ 2 - 3m ≤ 7


32. Solve:
  3/2 ≥  1 - n > -2



33. Solve:
   5n - 1 > 0 and 4n + 2 < 0



34.Solve:
  3y + 5 ≥ 2y + 1 > y - 1



35.Solve:
  3z + 7 ≤ 4z and 3z + 7 > -4z



36.Solve:
  -5 < 2(2-s) + 1 ≤ 9



37.Solve:
  y - 3 all over 6 ≤ y - 1 or   y - 6 all over 3 ≤ y + 4  

Answer
31. -5/3 ≤ m ≤ 8/3

32. -4 > n ≥ 1/2

33. n > 1/5 and n < -1/2
(this can't be, so no solution)

34. y > - 2

35.  7 ≤ z and z > -1
(so 7 ≤ z)

36.  5 > s ≥ -2

37. y - 3/6 ≤ y - 1 or   y - 6/3 ≤ y + 4
y - 3 ≤ 6y - 6 or   y - 6 ≤ 3y + 12
3 ≤ 5y  or   - 18 ≤ 2y  
3/5 ≤ y  or  - 9 ≤ y
