Solve the following simultaneous equations.

${{\left( \frac{1}{x}+\frac{1}{y} \right)}^{2}}=157+\frac{2}{xy}$

${{\left( \frac{1}{x} \right)}^{2}}-{{\left( \frac{1}{y} \right)}^{2}}=85$

$\frac{4}{\sqrt[3]{x}}-\frac{3}{\sqrt[3]{y}}=9\frac{1}{2}$

$\frac{1}{6\left( \sqrt[3]{x} \right)}-\frac{2}{3\left( \sqrt[3]{y} \right)}=\frac{2}{3}$
