Take your original equation $\frac{x}{y} +\frac{y}{x} =-1$

and multiply both sides by $xy$ to remove the fractions. You are left with

$x^2+y^2=-xy$

So, $x^2+y^2=-xy$

Update: There is no numerical answer that can be found without being given a value for either x or y

We can use pythagorean theorem:

a^2 + b^2 = c^2

4 + 9 = c^2

13 = c^2

sqrt of 13 = c

Hope this helps!
