Solving Messy Equations: Combining Like Terms

This video covers the messiest-looking equations where x shows up in more than one place, such as this doozy: 2x-2+6x=-x+12. The key is to combine all the x terms together first, at which point it becomes like the two-step problems of the previous video. I will point out a few trick questions that teachers sometimes throw in to keep you on your toes/take away points.
