Ryder · Answer 1

X = y

x times y = y times z

we can use the number 2 for x

x=2

y=2

2 x 2 = 2 x z

4 = 2z

divide both sides by 2

2 = z

So, x=y=z=2 they are the same value no matter what number is used.

Prove x*y=y*z then x=y when z doesn't equal 0

Prove xy=yz then x=y when z doesn't equal 0
