Solve for x (complex solution)
x=-10\left(y^{2}+9\right)^{-\frac{1}{2}}y
x=10\left(y^{2}+9\right)^{-\frac{1}{2}}y\text{, }y\neq -3i\text{ and }y\neq 3i\text{ and }y\neq 0
Solve for y (complex solution)
y=3\left(100-x^{2}\right)^{-\frac{1}{2}}x
y=-3\left(100-x^{2}\right)^{-\frac{1}{2}}x\text{, }x\neq 0\text{ and }x\neq -10\text{ and }x\neq 10
Solve for x
x=\frac{10y}{\sqrt{y^{2}+9}}
x=-\frac{10y}{\sqrt{y^{2}+9}}\text{, }y\neq 0
Solve for y
y=\frac{3x}{\sqrt{100-x^{2}}}
y=-\frac{3x}{\sqrt{100-x^{2}}}\text{, }x\neq 0\text{ and }|x|<10
