Its incorrect because 30+5=35 and that is not equal to 20, its greater

@selenatorsmiler4life  I was saying that too. So I'm kinda confused...

anonymous · Answer

the "indirect proof" 
assume that it IS true, then derive a contradiction

anonymous · Answer

there is really not much to say, since the contradiction is obvious: $30+5\neq 20$

anonymous · Answer

Just explain what we said using complete sentences

anonymous · Answer

@satellite73 so then how would I put it?

anonymous · Answer

@selenatorsmiler4life  oh okay

anonymous · Answer

I think I got it a bit better.
It would be that it is similar because it is slightly equal to it.
Some where around there.
