How can I solve the nonlinear equations for X , Cs and Cc ?

xguess = [4. 5.]; % initial guess vector
function fx = MNLEfun(x)
Cc = x(1); 
Cs = x(2); 
umax = 0.8; 
Km = 4; 
Csoo = 10; 
Cso = 10; 
Ysc = 2; 
rg = umax * Cs * Cc / (Km + Cs); 
rs = 0 - (Ysc * rg); 
V = 5000; 
vo = 1000; 
D = vo / V;  
Cco = 4.33;
X = 1 - (Cs / Csoo);
fx(1,1) = (D * Cs - rg ); 
fx(2,1) = (D * (Cso - Cs) + rs); 
end

Thanks for the help

xguess = [4. 5.];
sol = fsolve(@MNLEfun, xguess);
CC = sol(1)
Cs = sol(2)
