That is what I get. I assume there is a minor error in your Alpha command, as I don't have access to Alpha I can't figure out in more detail.

Between A and T, B and T etc. there is a * which has not been copied here, I need to insert a space here to make it appear.

In any case I don't have Mathematica ... Is there a way to solve it with Wolfram Alpha?

Does Mathematica find a solution?

solve A* T^5+B* T^4+C* T^3+D* T^2=0, 5* A* T^4+4* B* T^3+3* C* T^2+2* D* T=0, A/6* T^6+B/5* T^5+C/4* T^4+D/3* T^3=-V, 1/42* A* T^7+1/30* B* T^6+1/20* C* T^5+1/12* D* T^4=Y for A,B,C,D

Thanks

E.

In Mathematica can be solved if formulated as: Solve[{AT^5+BT^4+CT^3+DT^2==0, 5AT^4+4BT^3+3CT^2+2DT==0, A/6T^6+B/5T^5+C/4T^4+D/3T^3==-V, 1/42AT^7+1/30BT^6+1/20CT^5+1/12DT^4==Y}, {A,B,C,D }]

Note that AT^5 could reference a variable AT instead of referring to A and T.
