In this we learn how to solve a simultaneous equations, or a system of linear equation. We will explore which way is best.
In this video series you will learn how to solve a system of two linear equations using elimination. This is also called the addition method because we are choosing to add.
A system of two equations in x and y can be solved by rearranging one equation to represent x in terms of y, and then substituting this expression for x into the other equation.
Sal shows how to solve a system of linear equations by graphing and looking for the point of intersection. This video is great on showing us how to solve systems by graphing.
