This lesson will be about solving systems using the substitution method.  You want to really practice and make sure you master this topic as it will come up over and over again in algebra and beyond.  I will be teaching you various ways to solve systems but for now you really want to master the graphing method, the substitution method and the combination method.  Many students have problems with the equation solving steps in this topic so you might want to review literal equations and formulas if needed (the lesson is in the equations chapter). Take great notes and you must practice solving systems a lot to really be confident about your skills.
