Answer :

(i) -2x > 5, x є Z


Multiply both the sides by -1 in above equation,


-2x(-1) > 5(-1)


2x < -5


Dividing both the sides by 2 in above equation,



x <


x < 2.5


Since, x is an integer


Therefore, possible values of x can be


x = {…, -2, -1, 0, 1, 2}



(ii) -2x > 5, x є R


Multiply both the sides by -1 in above equation,


-2x(-1) > 5(-1)


2x < -5


Dividing both the sides by 2 in above equation,



x <


Therefore,
