<h2>
Explanation:</h2>
Let's use the following System of Linear Equations in Two Variables in order to solve this exercise:

So we can graph these lines using two points.
For eq (1):

So graph a line that passes through these two points. This is the red line shown below.
For eq (2):

So graph a line that passes through these two points. This is the blue line shown below.
<em>The solution of this system of equation is the point of intersection, which is (1,3)</em>
