-(k1*k4*(1+k2))/(k2*(1+k1))=-1.79;
k1*(1+k2)/(k2*(1+k1))=1.12;
k1*k4*(1+k2)*(1+k3)/(k2*(1+k1)*(k3*k4-1))=2.56;
k3=k4;
这个方程的解能求吗?

s1 = -(k1*k4*(1+k2))/(k2*(1+k1))==-1.79;
s2 = k1*(1+k2)/(k2*(1+k1))==1.12;
s3 = k1*k4*(1+k2)*(1+k3)/(k2*(1+k1)*(k3*k4-1))==2.56;
s4 = k3==k4;
s = solve(s1,s2,s3,s4);
s.k1
