Khan Academy: "Simple Elimination Practice"

Watch these videos and take notes. In the first video, you will see an example of a system that is ideal for solving by elimination. The system discussed in the second video can also be solved by elimination, but an extra step is required before one of the variables can be eliminated. In the third example, both equations need to be replaced by equivalent in order to eliminate one of the variables.
