Best ResponseYou've already chosen the best response.0@ParthKohli seems right. Dividing both the sides by z is possible only when z is not equal to 0. Cuz, any number divided by 0 is not defined. Do reply if you get another proof.

Best ResponseYou've already chosen the best response.0we can write x/y=z/z so x/y=1 so x=y

Best ResponseYou've already chosen the best response.0ok man i got the proof wanna share with you guyssssss as xz = yz > given xz yz = 0 (xy)z = 0 as z is not equal to zero> given thus xy=0 => x=y hence proved thanks to all of you. thanks alot for your time
