Question

if x=y and y=z

then prove that x=z

Answer 1

given that

$x = y.............(1) \\ \\ and \\ \\ y = z.............(2) \\ \\ adding \: equation \: (1) \: and \: equation \: (2) \\ \\ x + y = y + z \\ \\ = > x + y - y = z \\ \\ = > x = z \: \: \: \: \: \\ \\ proved \: hope \: it \: helps....$

Answer 2

Answer :-

__________________________

Given :-

x = y ---- ( i )

y = z ---- ( ii )

To prove :-

x = z

Salutation :-

from ( ii ) we get ,

y = z

•°• x = z [ °•° x = y --- ( i )[ Proved ]]
