Correction: Symbolic evaluation without units will give you a solution (I got confused with N and lbf), but a different one, as your system has no unique solution.Symbolic eval with units returns a...

No need to calculate the reduced row echolon form manually, you may use rref.But as rank(M)=rank(ME)=2<3 we already know, that we have an infinite number of solutions. You may google "Rouché-Capelli...

I get the same (wrong) result as you. Thats what happens quite often with numeric methods. The symbolics would refuse to evaluate that expression (with an inappropriate error messoge, though).But why...
