linsolve fails

[melonedo]

When I was trying the tutorials in examples/solvers.md, I find these are probably broken.
solve seems to be good:

julia> @vars x y z
julia> solve([x + y + z - 1, x + y + 2*z - 3 ], (x, y, z))
Dict{Any,Any} with 2 entries:
  z => 2
  x => -y - 1

linsolve produces an empty set (this is also shown in the notebook version of tutorial):

julia> linsolve([x + y + z - 1, x + y + 2*z - 3 ], (x, y, z))
∅

solveset can't even run:

solveset([x + y + z - 1, x + y + 2*z - 3 ], (x, y, z))
ERROR: MethodError: no method matching solveset(::Array{Sym,1}, ::Tuple{Sym,Sym,Sym})
Closest candidates are:
  solveset(::SymPy.SymbolicObject, ::Any...; kwargs...) at C:\Users\melonedo\.julia\packages\SymPy\QNFlL\src\importexport.jl:96
Stacktrace:

Are there any caveats in using this module?

Thanks for pointing these out. I need to integrate the examples into the testing framework, as changes to the underlying sympy package can necessitate changes to this package. I'll look into these specific issues and address. There certainly have been changes.
