We have learned two algebraic methods of solving systems of equations. The yesterday we learned the method of elimination or addition and subtraction. Today we learned the method of substitution. For a detailed explanation of each of these methods you can visit this site.

Then if you want more practice on elimination go to the sparknotes site. There is also more practice for substitution at sparknotes.

Have a great weekend and don't forget to watch Numb3ers.
