Sorry, I don't remember how to solve this algebraically but you can use your graphing calculator for this!

First step is to click on the
y= button and it's gonna take you to this window.

You then have to input both formulas and once you're done, click
graph and it will graph it for you. I would recommend clicking the
window button beforehand and changing the Xmin/Ymin and Xmax/Ymax to -100 and 100 respectively.

Once you do that, click
2nd and then click the
trace button and then click
intersect. Click
enter 3 times and then it will show you the coordinates of where they intersect.

I got (x = -9) and (y = 53)
