I-solve ang r (complex solution)
r=\frac{\sqrt{55}\left(-x-18000\right)^{-\frac{1}{2}}\left(-\sqrt{55\left(-x-18000\right)}-1100i\right)}{55}
r=\frac{\sqrt{55}\left(-x-18000\right)^{-\frac{1}{2}}\left(-\sqrt{55\left(-x-18000\right)}+1100i\right)}{55}\text{, }x\neq -18000
I-solve ang r
r=\frac{\sqrt{\frac{55}{x+18000}}\left(-\sqrt{55\left(x+18000\right)}+1100\right)}{55}
r=\frac{\sqrt{\frac{55}{x+18000}}\left(-\sqrt{55\left(x+18000\right)}-1100\right)}{55}\text{, }x>-18000
I-solve ang x
x=-\frac{2000\left(9r^{2}+18r-2\right)}{\left(r+1\right)^{2}}
