- How can I find the extrema of the function?

Hi, I'm differentiating the "z" function to find extreme points but after solving the first partial derivatives with respect to "x" and "y" and also the "x" variable of the system, I can't find "y" (still in the system) using "ln" (natural logarithm).

The question is can I differentiate both sides and easily write what "y" is or I can't use that method to solve it?

The problem: y^2=ln(1-y^2)

This is how I've got here (picture):
