systems of nonlinear equations
i need to help i have tried this problem but i cannot find the right answer i need to determine the real solutions for this:
multipy the bottom equation by 4
add the equations
solve for x, you get +-sqrt2
put each of those values into the first equation, and solve for y.
I will do the -sqrt2=x for you.
now do the solution of y for x=+sqrt2
