1. You know it is impossible to graph anything using a keyboard.

Do this:

1-Isolate y for both equations.

2-Select about 3 values for x and solve for y in both equations.

3-Then graph the points that you find on the xy-plane.

4-Connect the points with a solid line.

5-The solution of this system of linear equations in two variable will be where the two graphs meet or cross each other on the xy-plane.

Got it?
