I figured the missing values were integers & it was then clear that they must be small. There were not a lot of options left: 2 & 4, 3 & 9, 4 & 16. I got it right first go after this.


Pauli

I had a similar path, slightly different though. From both equations I figured both x and y had to be perfect squares. Then looked at the first equation and y had to be less than 7, which left me with 4 as the only answer, leading to sqrt(x)=3. Visually tested the 2nd equation and turns out it worked.
