Answer 1

$\displaystyle \left \{ {{x-2y+1=0} \atop {\frac{1}{x}+\frac{1}{y}-\frac{5}{6}=0 }} \right. \\\\\left \{ {{x=2y-1} \atop {\frac{1}{x}+\frac{1}{y}-\frac{5}{6}=0 }} \right. \\\\\frac{1}{2y-1}+\frac{1}{y}-\frac{5}{6}=0\\\\y=\frac{3}{10},y=2\\\\x=2*\frac{3}{10}-1,x=2*2-1\\\\x=-\frac{2}{5},x=3\\\\(x_1,y_1)=(-\frac{2}{5},\frac{3}{10}),(x_2,y_2)=(3,2)$
