Answer 2

ответ получается (6 , -3) и (6 , 3)

$\left \{ {{x - y^{2}=-3 } \atop {xy^{2}=54 }} \right. \\\\\left \{ {{x = -3 + y^{2} } \atop {xy^{2} = 54 }} \right. \\\\(-3 + y^{2} ) * y^{2} = 54\\\\y = -3\\y = 3\\\\x = -3+(-3)^{2} \\x = -3 + 3^{2} \\\\x = 6\\x = 6\\\\(x1 , y1) = (6 , - 3)\\(x2 , y2) = (6 , 3)\\\\\left \{ {{6 - ( -3)^{2}= -3 } \atop {6 * (-3)^{2}= 54 }} \right. \\\left \{ {{6 -3^{2}=-3 } \atop {6 * 3^{2}=54 }} \right. \\\\\left \{ {{-3 = -3} \atop {54 = 54}} \right. \\\left \{ {{-3 = -3} \atop {54 = 54}} \right. \\$
