Proof: Transitive Property of Equality Variation 2

Let's prove the following theorem:

if the following are true:

a = b
a = c

then b = c

Proof:

Given

1	a = b
2	a = c

Proof Table

#	Claim	Reason
1	b = a	if a = b, then b = a (Symmetric Property of Equality)
2	b = c	if a = c and b = a, then b = c (Transitive Property of Equality)
