y - x=2
x²-2xy =3​

Answer 1

$left { {{y-x=2} atop {x^{2}-2xy=3 }} right.\\left { {{y=x+2} atop {x^{2}-2x*(x+2)=3}} right.\\left { {{y=x+2} atop {x^{2}-2x^{2}-4x-3=0}} right. \\left { {{y=x+2} atop {-x^{2}-4x-3=0 }} right.\\left { {{y=x+2} atop {x^{2}+4x+3=0}} right.\\left { {{y=x+2} atop {left[begin{array}{ccc}x_{1}=-1 \x_{2}=-3 end{array}right }} right.$

$left[begin{array}{ccc}left { {{x_{1}=-1 } atop {y_{1}=-1+2=1 }} right. \left { {{x_{2}=-3} atop {y_{2}=-3+2=-1 }} right. end{array}right\\Otvet:boxed{(-1;1),(-3;-1)}$
