题目若实数xxx,yyy满足{x2+xy+y2=7x2−xy+y2=3\left\{\begin{array}{l}{x^2}+xy+{y^2}=7\\{x^2}-xy+{y^2}=3\end{array}\right.{x2+xy+y2=7x2−xy+y2=3,则x2022+y2022x^{2022}+y^{2022}x2022+y2022的值是（ ）A.22022+12^{2022}+122022+1B.22022−12^{2022}-122022−1C.−22022+1-2^{2022}+1−22022+1D.−22022−1-2^{2022}-1−22022−1知识点：解二元一次方程组——代入消元法章节：方程与不等式 / 二元一次方程组
