7.1 Nice job! Now going deeper into systems of equations with word problems.

Well done on your quizzes last week!  I observed that a number of you took the time to use all three tools (function, table & graph) to solve the word problems on quiz.  Your process is getting stronger as you make mistakes, catch them and continue to work hard on your conceptual understanding of what you are doing.

You may be starting to realize that algebra is getting rather time-consuming.  This week there will be even more steps to solve our assigned tasks. As it gets more complicated it is important you understand what you are doing and why so you can remember the process for solving systems of equations.

Chapter 7 - Section 1
Basically we are combining the questions you answered on your quiz.  You will be solving word problems that have 2 linear equations instead of just one linear equation.

If this seems totally new to you, please review the videos from last week:
