# Algebra I – Systems of Linear Equations Video Study Guide | Complete Playlist

This playlist consists of 22 videos all about systems of linear equations.  Teachers can use these videos to support their lesson plans and engage students.  These videos each cover specific topics and concepts learned in Algebra I classes.  The playlist is an excellent resource for students to review or study for a test or final.  For Common Core alignment, see below.  By the end of this playlist, students will be able to understand and solve problems involving linear equations.

# Common Core State Standards Alignment

## CCSS.MATH.CONTENT.HSA.REI.C.6

Solve systems of linear equations exactly and approximately (e.g., with graphs), focusing on pairs of linear equations in two variables.

## CCSS.MATH.CONTENT.HSA.REI.C.7

Solve a simple system consisting of a linear equation and a quadratic equation in two variables algebraically and graphically. For example, find the points of intersection between the line y = -3x and the circle x2 + y2 = 3.

## CCSS.MATH.CONTENT.HSA.REI.C.8

(+) Represent a system of linear equations as a single matrix equation in a vector variable.

## CCSS.MATH.CONTENT.HSA.REI.C.9

(+) Find the inverse of a matrix if it exists and use it to solve systems of linear equations (using technology for matrices of dimension 3 × 3 or greater).
