Question

I am calculating membrane water flux using fsolve but MATLAB gave me a negative value of water flux (Jw) as follows. I don't know how to avoid these negative solution from non-linear equation so I would like to know how to solve it correctly
Here are MATLAB codes I used to calculate function [Jw,q]=jw_q_solve(Tf,Tp,P,B,Km,d,h) %Jw, water flux [L.m^-2.h^-1] %q, heat...

Question

How can solve this system of differential equations with two variables x, y? I will attach a photo to make it clearer.
-dx/dt = -0.6208*y^0.75*x^3; -dy/dt = -3*0.6208*y^0.75*x^3; y(0) == 0.48; x(0) == 1.44;
