Question: Is It Abel again :(( ?

 

I have the data set and  a systems of ODE ( 2 diff. eqn.)

is there any solution for these two equations simultaneously ?

How can I fit the data and evaluate the constants numerically, and how can I plot this ?

 diff(x(t),t)=a*b*[X(t)^2-(Xo+Yo)*X(t)+X(t)*Y(t)]/[b*X(t)+c*Y(t)];

 diff(Y(t),t)=a*c*[Y(t)^2-(Xo+Yo)*Y(t)-X(t)*Y(t)]/[b*X(t)+c*Y(t)];
