Systems 04: Elimination 2
In this video, we are going to learn about solving systems of equations using advanced elimination techniques.
We will list the steps in using elimination for solving any system of linear equations with two variables
We solve one system where one equation needs to be multiplied by a number before we can eliminate a variable
We solve another example where both equations must be multiplied by numbers in order to eliminate a variable.
Now it's your turn!
