Solve for x (complex solution)
x=-\frac{i\sqrt{7y-21}\sqrt{y+5}}{4}+2
x=\frac{i\sqrt{7y-21}\sqrt{y+5}}{4}+2
Solve for y (complex solution)
y=-\frac{4\sqrt{21+28x-7x^{2}}}{7}-1
y=\frac{4\sqrt{21+28x-7x^{2}}}{7}-1
Solve for x
x=-\frac{\sqrt{105-14y-7y^{2}}}{4}+2
x=\frac{\sqrt{105-14y-7y^{2}}}{4}+2\text{, }y\geq -5\text{ and }y\leq 3
Solve for y
y=-\frac{4\sqrt{21+28x-7x^{2}}}{7}-1
y=\frac{4\sqrt{21+28x-7x^{2}}}{7}-1\text{, }x\geq 2-\sqrt{7}\text{ and }x\leq \sqrt{7}+2
