Question

determine the real solutions to the following nonlinear systems.

Answer 1

\[2x^2+y^2=5 \] and \[x^2-2y^2=-14\]

Answer 2

to me, I solve as if I don't see the exponent, jut time 2 to the first equation, add them together , solve for x , then plug back solve for y. And reject the imaginary solution. That's it
