Presentation transcript:

Session How did you prepare for the test last class? Was the test easier than you expected or harder than you expected or about what you thought it would be? Explain your answer. 2. If you got to choose which method to use to solve a system, how would you go about making your decision? What makes you choose linear combination over graphing? Why would you choose substitution over linear combination?

Steps for solving word problems: 1. Indicate what each variable stands for. 2.Write a system of 2 equations that can be used to solve the problem. 3.Solve the system. 5. Check your work in both original equations. 4. State your solution in sentence form.
