Solving systems of equations... Survivor-style. Sorry, "y"... you're out of here. Grab your torch. The tribe has spoken. Sounds complicated doesn't it? Well it's not. All you do is multiply one equation by a number to make the coefficients of one variable the same. Next you just add the equations together, and you have eliminated one variable. You solve for the other, and plug it in to solve for the first. Still confused? watch the video.
