Answer 1

$\left \{ {{x+y+5=0} \atop {9x^{2}-4y^{2}+5x+10=0}} \right.\\\\\left \{ {{y=-x-5} \atop {9x^{2}-4(-x-5)^{2}+5x+10=0}} \right.\\\\\left \{ {{y=-x-5} \atop {9x^{2}-4x^{2}-40x-100+5x+10=0}} \right.\\\\\left \{ {{y=-x-5} \atop {5x^{2}-35x-90=0 }} \right.\\\\\left \{ {{y=-x-5} \atop {x^{2}-7x-18=0}} \right.\\\\1)\left \{ {{x_{1} =-2} \atop {y=-(-2)-5}} \right.\\\\\left \{ {{x_{1}=-2 } \atop {y_{1}=-3 }} \right.\\\\2)\left \{ {{x_{2}=9 } \atop {y)-9-5}} \right.$

$\left \{ {{x_{2}=9} \atop {y_{2}=-14}} \right.\\\\Otvet:\boxed{(-2;-3),(9;-14)}$
