This is easy because they y's will cancel out. I love this method it's the easiest one out of substitution, and graphing. 

So the Y's will cancel out an you will get x=2. Then you plug the 2 in for x in the first equation. so it will 2+y-3. You subtract 2 from both sides to get y=1.

So the ordered pair is(2,1)   :)
