\left\{ \begin{array} { l } { ( x - 1 ) ^ { 2 } + y ^ { 2 } = 5 } \\ { ( x + 7 ) ^ { 2 } + ( y - 2 ) ^ { 2 } = 20 } \end{array} \right.
Solve for x, y (complex solution)
x=-\frac{3\sqrt{161}i}{68}-\frac{36}{17}\approx -2.117647059-0.559790186i\text{, }y=-\frac{3\sqrt{161}i}{17}+\frac{53}{68}\approx 0.779411765-2.239160742i
x=\frac{3\sqrt{161}i}{68}-\frac{36}{17}\approx -2.117647059+0.559790186i\text{, }y=\frac{3\sqrt{161}i}{17}+\frac{53}{68}\approx 0.779411765+2.239160742i
