Answer 1

X = -1

x = 1

y = 19

Пошаговое объяснение:

$\left \{ {{8x^{2} +y = 27} \atop {19x^{2} - y = 0}} \right.$

$\left \{ {{y=27 - 8x^{2} } \atop {19x^{2} -y=0}} \right.$

19$x^{2}$-(27-8$x^{2}$) = 0

27$x^{2}$ - 27 = 0

x = -1

x = 1

============

y = 27 - 8*$(-1)^{2}$

y = 27 - 8 * $(1)^{2}$

y = 19

y = 19

Answer 2

8x²+y=27

+

19x²-y=0

27x²=27

19x²-y=0

x=1

19*1-y=0

x=1

y=19
