Berapa himpunan penyelesaian dari sistem persamaan linear 2 variahp x²+y²=5 dan x²-y²=3

Metode Eliminasi


[tex]$\begin{align}x^2+y^2&=5\\\underline{x^2-y^2&\underline{\ =3\ \ -}}\\2y^2&=2\\y^2&=1\\y&=\pm1\\\\\\x^2+y^2&=5\\\underline{x^2-y^2&\underline{\ =3\ \ +}}\\2x^2&=8\\x^2&=4\\x&=\pm2\end[/tex]


[tex]\boxed{\text{HP}=\{\pm2,\ \pm1\}}[/tex]
