Systems of Equations

If you do not know what systems of equations are please do not send me a handshake. The last answer i bought was wrong.

Part 1

Write your own system of equations problem.  Start with two known values that would represent the two variables.  Write two equations using both variables; be sure these would make a true statement.

Part 2

Describe when it would be easier to use the substitution method versus the elimination method. Give an example describing how to choose which method is best given the system that is provided. Also, the graphing method also provides a way of solving systems of equations. Describe why this is not always the best method to solve a systems of equations.
