## Question:solve simultaneous eq

Maple 16

Hi, I would like to solve for i and c in this system. But whenever I try to solve it, it give a warning message "the solution may have been lost"

eq:={rho*(psi*i+psi*epsilon*c)*(1-i-phi*((`&vartheta;`+mu)*(mu+delta)*(1-i-c)-beta*c*(`&vartheta;`+mu)-xi*i*(mu+delta))/((`&vartheta;`+mu)*(mu+delta)*(phi+omega+`&epsilon;`*psi*i+`&epsilon;`*epsilon*psi*c+mu))-c-(tau*`&vartheta;`*xi*i+beta*c*`&vartheta;`+beta*c*mu)/((`&vartheta;`+mu)*(mu+delta))-xi*i/(`&vartheta;`+mu)+`&epsilon;`*phi*((`&vartheta;`+mu)*(mu+delta)*(1-i-c)-beta*c*(`&vartheta;`+mu)-xi*i*(mu+delta))/((`&vartheta;`+mu)*(mu+delta)*(phi+omega+`&epsilon;`*psi*i+`&epsilon;`*epsilon*psi*c+mu)))-(PI+beta+mu+alpha*i)*c+alpha*i*c = 0, (1-rho)*(psi*i+psi*epsilon*c)*(1-i-phi*((`&vartheta;`+mu)*(mu+delta)*(1-i-c)-beta*c*(`&vartheta;`+mu)-xi*i*(mu+delta))/((`&vartheta;`+mu)*(mu+delta)*(phi+omega+`&epsilon;`*psi*i+`&epsilon;`*epsilon*psi*c+mu))-c-(tau*`&vartheta;`*xi*i+beta*c*`&vartheta;`+beta*c*mu)/((`&vartheta;`+mu)*(mu+delta))-xi*i/(`&vartheta;`+mu)+`&epsilon;`*phi*((`&vartheta;`+mu)*(mu+delta)*(1-i-c)-beta*c*(`&vartheta;`+mu)-xi*i*(mu+delta))/((`&vartheta;`+mu)*(mu+delta)*(phi+omega+`&epsilon;`*psi*i+`&epsilon;`*epsilon*psi*c+mu)))+PI*c+(1-tau)*`&vartheta;`*xi*i/(`&vartheta;`+mu)-(alpha+xi+mu+alpha*i)*i+alpha*i^2 = 0}

solve(eq, [i, c])
