Ch 6 Systems
This chapter introduces you to the idea of solving two equations with two variables. The skills mastered from chapter two are very important for this chapter.
Solving Systems by Substitution Part 1
Here is an easy problem.
Solving Systems by Substitution Part 2
Here is a medium problem. It's considered medium in difficultly because an equation is solved for X instead of Y.
Solving Systems by Substitution Part 3
Here is a difficult problem. It's considered difficult because you have to rewrite an equation before you can substitute.
Solving Systems by Elimination Part 1
This is an easy elimination problem.
Solving Systems by Elimination Part 2
Here is a medium elimination problem. You have to do some work before you can eliminate.
Solving Systems by Elimination Part 3a
Here is a version of a difficult elimination problem.
Solving Systems by Elimination Part 3b
Here is another version of a difficult elimination problem.
Applying Systems Part 1
Here is one example of a complex system word problem.
Applying Systems Part 2
Here is another example of a complex system word problem.
