Techincal Difficulties

I have to apologize, I just discovered that the microphone on my laptop has been dead for a few days.  That means that many of the videos I've been posting are silent films.  I'm very sorry and assure students and parents that I've got a temporary fix for future videos.  If there is demand I can go back and put in an audio track for some of the videos.

    What do I do when the second equation has the x on the other side than the first equation when dealing with elimination?

    You need to subract the x from both sides so that it IS in standard form. Once you do that, all those on Riddle 161 can be eliminated without having to multiply by something.
