Solve for x, y
x=8\text{, }y=-3
x=\frac{2^{\frac{2}{3}}\left(\sqrt[3]{3\sqrt{18993}+7355}+\sqrt[3]{7355-3\sqrt{18993}}-8\sqrt[3]{2}\right)}{6}\approx 7.619975104\text{, }y=\frac{\sqrt[3]{2}\left(16\sqrt[3]{2}\left(\sqrt[3]{3\sqrt{18993}+7355}+\sqrt[3]{7355-3\sqrt{18993}}\right)-\left(3\sqrt{18993}+7355\right)^{\frac{2}{3}}-\left(7355-3\sqrt{18993}\right)^{\frac{2}{3}}\right)+18}{18}\approx 2.935979411
