Linear equation with Kronecker delta, Plz help

if (f,g) are variables,
The constants are: A,B,C,D, (vary with i,&j) S1,S2 (not depended on i&j) .
Sij = Kroencker delta (=1, when i=j, & =0:if i≠j )


Aij*fj + Bij*gj =S1. S0j
Cij*fj + Dij*gj =S2. S0j


i,j=0,1,2,3.............N

Is it correct what I am getting [that the values of ( fj, & gj =0 for j≠0 !!)

Also, want to check that the equations are not in a matrix form: row from A * column vector of, f, Plus row from B * column vector of g.

I was checking the equation for an example (solving for N=2, and : ktt.a =1, ktb.a=kbt.a= -3.4744, and kbb.a=18.56) and getting results very far from the solution.

I do not what I am missing

Please see the attached

Thanks
