(b) Given that y is an integer and −3 < 2y − 6 < 4 , list the possible values of y.

Can anyone help me in that question.

Yar simple is that , what you do on one side, do on both of the sides
-3<2y-6<4
= 3<2y<10 (add six on both sides)
= 3/2<y<5 (divide both sides by 2)
POSSIBLE VALUES OF Y =2 OR 3

Samajh aai. IT WAS TO EASY.PAPER KE BARE MAIN ZYADA TENSE MAT HO.
