Explanation:
First, you can graph the two equations by finding the respective x-coordinate when y=0 and 1. As the equation is linear (for both x and y), you can just draw a straight line that passes through both points.
From the picture, we can see that the two graphs intersect at the point (3,2). Hence, the solution for the simultaneous equation is
