2(2х^2+4у^2)=24х

2*24=24х

Х=2

Если х=2, то 4у^2=24-8=16,

У=2 или -2

Answer 2

$left { {{2x^2+4y^2=24} atop {4x^2+8y^2=24x}} right.; left { {{x^2+2y^2=12} atop {x^2+2y^2=6x}} right. ; left { {{x^2+2y^2=12} atop {6x=12}} right. left { {{2y^2=12-x^2} atop {x=2}} right. \\left { {{2y^2=8} atop {x=2}} right. ; left { {{y^2=4} atop {x=2}} right. ; left { {{y=pm 2} atop {x=2}} right. ; ; Rightarrow ; ; (-2,2); ,; ; (2,2)$
