Hello. So I have this weird task given to me (at least for me, it's not understandable) and as far as I know, all of my classmates were struggling with it too. Could someone please explain how do I do this kind of a task?

My example is here:

(The answer to this one is written in the brackets.)

Thank you!

$\sqrt{(x + 3)^2 + y^2}+ \sqrt{y^2 + (x - 3)^2} = 8$; $\text{ }($Atb.: \(\displaystyle \frac{x^2}{16} + \frac{y^2}{7}= 1\))
