Solving system of linear equations | A re-introduction of the method of elimination
The method of elimination is a common method in solving system of equations. However, most students may not be aware that there is nothing new. Rather, it is a way of thinking, reducing this new challenge to something that we know how to deal with - reduce it to one equation with one known!
The video not only serve as showing this method again, but also making students aware of this technique. As reduction is a powerful way to solve problems when we need to reduce the problem to something easier to manage.
