I am numerically solving a nonlinear system of nine equations. How long can I expect it to take?

I have run it for 30 minutes and it has not solved yet.

Here is the system of equations:

**0=Lambda-mu.*S-beta.*(H+C+C1+C2).*(S./N)-tau.*(T+C).*(S./N);**

**0=tau.*(T+C).*(S./N)-beta.*(H+C+C1+C2).*(T./N)-(mu+mu_T).*T;**

**0=beta.*(H+C+C1+C2).*(S./N)-tau.*(T+C).*(H./N)-(mu+mu_A).*H;**

**0=beta.*(H+C+C1+C2).*(T./N)+tau.*(T+C).*(H./N)-(mu+psi.*mu_A+mu_T+lambda_T).*C;**

**0=lambda_T.*C-(mu+mu_A+rho_1+eta_1).*C1;**

**0=rho_1.*C1-(mu+mu_A+rho_2+eta_2).*C2;**

**0=eta_1.*C1-(mu+rho_1+gamma).*CT1;**

**0=eta_2.*C2-(mu+rho_2+gamma.*(rho_1)./(rho_1+rho_2)).*CT2+(rho_1).*CT1;**

**0 = N - S - T - H - C - C1 - C2 - CT1 - CT2**;

and I have numeric values for **Lambda, beta, tau, mu, mu_T, mu_A, rho_1, rho_2, psi, gamma.** The only parameters left are **eta_1, eta_2**.

Thank you.
