What are the different ways you can solve a system of linear equations in two variables? what is the process for solving a system using each method? what are the benefits and limitations to each method? when is it best to use each method? what are the different types of solutions that you can get when you solve a system of linear equations? describe the graphs of these different types of systems. explain how using systems of equations might you find a better deal on renting a car . describe different situations in the real world that could be modeled and solved by a system of equations in two variables ( do not use the example listed before).
