you are learning about systems of equations and three methods for solving them: graphing, substitution, and addition. Compare and contrast the three methods by discussing the following: Is one method easier than the others for all systems, or does it depend on the system? If it depends on the system, how could you tell before you begin solving the system which solution method would be the most efficient? How is it possible to tell by inspection (look at it) whether...
