The Method of Elimination ( also called reduction ) consists in combining two equations in such a way
that one of the variables is eliminated. We can add or subtract two equations or we can multiply the
equations by a number and then add or subtract them to cancel one of the variables.

In this video, we do three examples with systems of equations of two variables and two unknowns and
two examples with systems of equations with three equations and three unknowns. Some of them end up
having a unique solution, some no solution (inconsistent) and some, infinite solutions. Pay attention
and learn how to write the infinite number of solutions.
