    This uses certain axioms.

    Divide both sides by \(\rm z\).

    @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.

    Take z inverse operation xz * z^-1 = yz * z^-1 x = y

    we can write x/y=z/z so x/y=1 so x=y

    ok man i got the proof wanna share with you guyssssss as xz = yz -----> given xz- yz = 0 (x-y)z = 0 as z is not equal to zero-----> given thus x-y=0 => x=y hence proved thanks to all of you. thanks alot for your time
