anonymous · Answer

we know that; 3y^2=187-7x^2
and 3y^2-7x=47
187-7x^2-7x=47
can you continue??

anonymous · Answer

i have no idea how to continue :( ha

precal · Answer

why not just graph them and find those points of intersections

anonymous · Answer

140-7x^2-7x=0
20-x^2-x=0
what are the values of x??

precal · Answer

or better yet just sub your values and find out which ones are true in all equations

anonymous · Answer

x=-5,4

anonymous · Answer

what comes after that? @marsss

anonymous · Answer

@precal i'll try that afterwards, thanks :)

anonymous · Answer

right now you should plug those and find the values of y. ok??

anonymous · Answer

one minute

anonymous · Answer

when x=4 y=5,-5

anonymous · Answer

when x=-5 y=2,-2

anonymous · Answer

ok, you found :) answer is second one.

anonymous · Answer

so which choice would that be in the multiple choice?

anonymous · Answer

i said, second one.

anonymous · Answer

ohhh i thought you meant the second equation i'm sorry
