# Interactive video lesson plan for: Cramer's Rule - 2x2 & 3x3 Matrices - Solving Systems of Linear Equations - 2 & 3 Variables

#### Activity overview:

This algebra video tutorial shows you how to solve systems of linear equations with 2 or 3 variables using cramer's rule. This video contains plenty of examples and practice problems for you to work on.

Here is a list of topics:
1. Cramer's Rule - Formulas & Equations
2. Converting Linear Equations Into 2x2 & 3x3 Matrices
3. How to calculate the determinants of a 2x2 matrix - D, Dx, & Dy
4. Determinant of a 3x3 Matrix - Converting it into 3 smaller 2 x 2 matrices
5. Simultaneous Equations - System of Linear Equations with 3 Variables - x, y, and z

### Spiral Reviews by Teachers and Digital Learning Coaches

@kklaster

Tried out the canvas response option on @SpiralEducation & it's so awesome! Add text or drawings AND annotate an image! #R10tech

Using @SpiralEducation in class for math review. Student approved! Thumbs up! Thanks.

@ordmiss

Absolutely amazing collaboration from year 10 today. 100% engagement and constant smiles from all #lovetsla #spiral

@strykerstennis

Students show better Interpersonal Writing skills than Speaking via @SpiralEducation Great #data #langchat folks!

A good tool for supporting active #learning.
