Solve 3x + 8 > 2, when
(i) x is an integer.        (ii) x is a real number.     Â
        3x + 8 > 2
       3x > 2 - 8  3x > - 6  x > -2
∴  (i) When       Â
     x = -1, 0, -1, 2, 3, ........
     The solution set isÂ
  (ii)  WhenÂ
      The solution set isÂ
   Â
3(x – 1) ≤ 2 (x – 3)
     Â
Hence,Â
Solve -12x > 30, when
(i) x is a natural number. Â Â Â Â Â Â (ii) x is an integer.
-12x > 30
                          (∵ -12 < 0)
    Â
∴ (i) When , there is no solution
∴ The solution set is .
(ii) Â Â WhenÂ
     The solution set isÂ
Solve 5x – 3 < 7, when
(i) x is an integer.        (ii) x is a real number.     Â
5x – 3 < 7
        5x – 3 < 7  5x < 10  x<2
∴   (i) WhenÂ
      The solution set isÂ
   (ii) WhenÂ
∴    The solution set isÂ
