Answer 2

If you assume that the conclusion is false, and you find a contradiction, then the only thing left to say is that the conclusion is true

Answer 3

So let's assume that the conclusion is false.

If this assumption is made, and it leads to making one of the given statements to be false, then we run into a contradiction (since the given statements are taken to be true)

Answer 4

Does that make sense?

Answer 5

yup thanks
