given 2x - 3b = 0 or x = 3b/2 and b<2
St 1: x> - 3 lets consider possible value of b if b = - 24 then x = - 36 so x> - 3 could be true but not must be true
St2: x<2 if b = 1.9 the x = 3*1.9/2 or x> 2 so this condition could be true but not must be true
St3: x = 3 for x = 3 we need b = 1 which is possible but again falls under could be true cause b can take any value Less than 2
St4: x<3 - - - - - - - > or 3b/2<3 we get (3b - 6)/2< 0 or 3b - 6< 0 Or b< 2 which is same as the original given condition
