Question

Let a, b, and c be integers with a not equal to 0. Prove that if ab|ac, then b|c.

Answer 1

since a not equal to 0

a = 1
b = 4
c = 2

4|2 = 2. Not sure how to use a general proof

Answer 5

It is the first excerise on top

Answer 6

if ac divisible by ab (ab | ac)

that means \(ac=d\cdot ab\) for some integer d

Answer 7

since a is not 0 ... we can divide both sides by a ---> c=db ---> b|c

Answer 8

I am not sure what you're trying to say..
