Only in that R4 and R5 are paralleled by R6, so the solution causes R4
and R5 to be a function of R6.

Drop R6 and there will be a singular solution.

Hmmm..singular usually means either infinite number of solutions or none
at all, anything but unique, you might work on your terminology. Vm is
worthless, it only sets ratio of R4/R5. The only determined solution is
for R6||(R4+R5), the equivalent lumped resistor load.

Duh! What did I just say?

And, yes, "singular" was a slip, should have said, "single".
