Question

It is known that aX c = 30 and that a = b . show that b x c = 30
. write Euclid`s axiom
that best illustrates this statement. Also , give two more axioms other than the axiom
used in the above situation.

Answer 1

we know that a×c=30 and a=b so we can put a=b in a×c=30 therefore b×c=30 by Euclid axiom that things which are equal to the same things are equal to each other thank you
