x^2+y^2=4
2x^2-y^2=8

(x,y)= ( ) and ( )

Answer 1

3x^2=12
x^2=4
x=2,-2
let me if you need more help

Answer 2

no that is what I had come up with as well thank you

Answer 3

both ways y=0 correct?

Answer 4

so you have x^2+y^2=4
y^2=4-x^2
y^2=4-4=0
y=0

yep
(2,0) and (-2,0)

Answer 5

awesome thank you so much
