- Algebra review - Solve systems of linear equations
- Solve Systems of Linear Equations Exactly and Approximately - Solving a system of linear equations means finding the point at which the two (or more) lines intersect. This happens when the same set of x and y values satisfy all the linear equations in the system. Students should be shown that a system of linear equations can be solved either through graphs or straight algebra, but that these two methods arrive at the same answer because they mean the same thing. The goal is to find the point at which the two lines intersect. A quiz is provided.
