I get (Maxima 5.11.0):
Inconsistent equations: (2)
-- an error. To debug this try debugmode(true);
(%i4) [r(1)=10, r(2)=5];
(%o4) [x[1,3]+x[1,2]+x[1,1]=10,x[2,3]+x[2,2]+x[2,1]=5]
Looking at your equations
(%i4) [r(1)=10, r(2)=5];
(%o4) [x[1,3]+x[1,2]+x[1,1]=10,x[2,3]+x[2,2]+x[2,1]=5]
I see that the second equation doesn't depend on X[1,1]
or X[1,2]. So the error seems okay; for example
(%i7) linsolve([x=6],[y]);
Inconsistent equations: (1)
What is the output of build_info() ?
