This is an entire packet of information that I use with my class when we are studying using matrices and determinants to solve systems of equations.
Within this packet, you will find:
a word problem that involves a system of 3 equations with 3 variables. This problem is written on one page that could be projected for your whole class
Scaffolded notes that you can use to teach your students about:
Solving systems by using inverse matrices
Using the calculator to find inverses and values of determinants
Finding the area of a triangle using the three vertices and a determinant
Finding the equation of a line using a determinant
Determining whether 3 points are collinear using a determinant
