9494 unread replies.137137 replies.
There are three ways of solving systems of linear equations: graphing, substitution, and elimination. This week we are studying substitution and elimination. Create a video or VoiceThread that explains in detail how to solve a problem using either of these two methods. You can find a problem to solve in your text book or on the internet. Show your step-by-step solution using one of the two methods. Make sure to include how you will check your solution. For your next two posts review and comment on at least two other videos or VoiceThreads!
