Answer
x=18.1; y=37.3
Work Step by Step
To graph the equations, plug the equations into $y_1$ and $y_2$ on the calculator. Next, select (2nd) and hit the "trace" key. Finally, select option 5 (intersect) to find the intersection between the two lines. (You may need to change the window to see the intersection point.)
Doing this, we see that the solution to the system of equations is:
$$(18.1,37.3)$$
