Answer 1

$left { {{ frac{6}{x+y}+ frac{5}{x-y}=7 } atop { frac{3}{x+y} }- frac{2}{x-y}=-1 } right.$

$left { {{ frac{6(x-y)+5(x+y)}{(x-y)(x+y)} =7} atop { frac{3(x-y)-2(x+y)}{(x-y)(x+y)} }=-1} right.$

$left { {{11x-y=7( x^{2} - y^{2}) } atop {7(5y-x)= 7(x^{2} - y^{2}) }} right.$

$11x-y=35y-7x$
$18x-36y=0$
$x=2y$  =>   $frac{6}{3y}+ frac{5}{y} = 7$
                      $3y=3 = textgreater y = 1; x=2$
