Giải các hệ phương trình sau:  \(\left\{ \begin{array}{l}\frac{1}{x} + \frac{1}{y} = \frac{8}{5}\\\frac{2}{x} - \frac{5}{y} = \frac{{ - 1}}{3}\end{array} \right.\)

A \(\left( {x;\,\,y} \right) = \left( {-\frac{{21}}{{23}};\frac{{105}}{{53}}} \right).\)

B \(\left( {x;\,\,y} \right) = \left( {\frac{{21}}{{23}};\frac{{105}}{{53}}} \right).\)

C \(\left( {x;\,\,y} \right) = \left( {\frac{{21}}{{23}};-\frac{{105}}{{53}}} \right).\)

D \(\left( {x;\,\,y} \right) = \left( {-\frac{{21}}{{23}};-\frac{{105}}{{53}}} \right).\)
