| param1 | param 2 | Answer |
| :---: | :---: | :---: |
| $x^{2}+y^{2}-4 y$ | $\|4 x-3 y\|+5 \sqrt{x^{2}+y^{2}-20 y+100}=30$ |  |
| $y^{2}+x^{2}+2 y$ | $\|4 y-3 x\|+5 \sqrt{x^{2}+y^{2}+20 y+100}=40$ |  |
| $x^{2}+y^{2}+2 x$ | $\|4 y+3 x\|+5 \sqrt{x^{2}+y^{2}+10 x+25}=15$ |  |
| $x^{2}+y^{2}-2 x$ | $\|4 x+3 y\|+5 \sqrt{x^{2}+y^{2}-10 x+25}=20$ |  |
