Решите систему уравнений:

$\left \{ {{x^{2} +y^{2} = 16} \atop {x^{2} +y = 25 }} \right. \\\\ \left \{ {{x^{2} +y^{2} = 16} \atop {x^{2} = 25-y }} \right. \\\\ \left \{ {{25 - y +y^{2} = 16} \atop {x^{2} = 25-y }} \right. \\\\ \left \{ {{ y^{2} - y + 9= 0} \atop {x^{2} = 25-y }} \right. \\\\ \left \{ {{D \ \textless \ 0 } \atop {x^{2} = 25-y }} \right. \\\\$
