cos(3*x)+cos(3*y)+cos(3*z)=0;
cos(5*x)+cos(5*y)+cos(5*z)=0;

What is the difference between this question and https://www.mathworks.com/matlabcentral/answers/394893-solving-trigonometric-non-linear-equations-in-matlab which is waiting for your response ?

I see that you edited the question to remove the formatting I had added in, but your equations are exactly the same as in your previous Question, so you need to explain why this is a new Question and why you did not respond to the previous suggestions.
