Concepts for February 23rd

Algebra I

Today we discussed
Our discussion about relations moved into equations as relations.  A solution of a relation that has two variables is any ordered pair that makes the equation true.  We reviewed solving literal equations, and solving for a particular variable.  A review of literal equations can be found here.

Pre-Algebra

Today we discussed
Our discussion about solving equations moved to working with variables on both sides.  We discussed strategies for moving the variable first, and which one to pick to start the process.  Remember, there are now three possibilities for solutions: you may have one solution, you may have an infinite number of solutions (all real numbers work), or you may have no solution at all.
