Below is the command I was trying to use to solve the set of equations. It doesn't give me an error or a result, I'm not sure if I am using it wrong or if solve is just the wrong command to use. Any advice would be greatly appreciated.

solve({beta*(chi^2*(exp(delta*rho))^2*delta^2-(1-chi*exp(delta*rho))*chi*exp(delta*rho)*delta^2) = 0.4e-1, beta*(-(1/12)*chi*exp(delta*rho)*delta^4*(1-chi*exp(delta*rho))+(7/12)*chi^2*(exp(delta*rho))^2*delta^4) = 0.8e-3, beta8*(-chi^2*(exp(delta*rho...
