Well you can say m+n=m+p and then add the additive inverse of m to both sides and continue The Art of Proof has this exact proof outlined on the home page funny enough, it references another proposition so be sure to click the link in the proof
Well then you have . Subtract from each side and you have it!
oh wow thanks a lot, I guess I didn't realize i could use that "transitive property of the equal sign" as it was never mentioned in class, but yeah that totally makes sense now
