Question

Ab=bd &ac=ad proof that ab=bc

Answer 1

Answer:

(ab=bc) proofed

Step-by-step explanation:

Given

ab= bd & ac= ad

To Proof that

ab =bc

ab=bd ( b common so cut it from both)

ac=ad (a common so cut a both sides)

Then

a=d (1equation)

c=d (2 equation)

Putting value s in ab=bc

db=db

Then , ab=bc Proofed

If helped , Thank you

otherwise sorry

Answer 2

Ab=bd .1
ac=ad .2

multiply 1 by c and 2 by b
so Abc=bcd .1
abc=abd .2
now divide 2 by 1
= abc/abc=abd/bcd
=1=ab/bc
now cross multiply
we get ab=bc proved
