NULL SET AND IDENTITY SET
LEARNIG GOAL: Student will use a show work-write step strategy to solve multi step equations. Then hopefully, they
will discover the “weird answers”. We will write what this means and substitute and solve using any number for
variable and show that it is true and any number and show that it is never true.

1.) What type of equations are these?
2.) What values work for the variable?
3.) In your own words tell your reader what
means. Include the steps to solve, what the
answer looks like, and how you proved all values for the variable work.
