​Leni:​ ​[sighs]​ You simply set the equation equal to x plus y equal to one, then substitute x plus y in the original equation with one. Then you solve for the remaining x, and substitute every x in the equation with what the answer is. In this case, it's 9.

​Lincoln:​ Thanks for that., I guess...

​Leni:​ What a waste of time that was. Even the most incomptetent of humans could solve that.

Lincoln: ​Hey! I was only asking for help!

​Leni:​ What you lack, Lincoln, is a brain.

Lincoln:​ [gives a frustrated frown]
