y^2+x=32
помогите решить

Answer 1

$\left \{ {{x=2-y} \atop {y^{2}+x= 3^{2} }} \right. \left \{ {{x=2-y} \atop { (2-y)^{2}+2-y=9 }} \right.* *(2-y)^{2} +2-y=9 4+4y- y^{2} +2-y=9 -y^{2} +4y-3=0 y^{2} - 4y+3=0 y_{1} =1 y_{2} =3* \left \{ {{ x_{1} =2-y} \atop { y_{1}=1 }} \right. \left \{ {{ x_{1}= 1 } \atop { y_{1}=1}} \right. \left \{ {{ x_{2=2-y} } \atop {y_{2=3} \left \{ {{ x_{2}=-1 } \atop { y_{2}=3 }} \right. .$
