You can use the function al_nlegsolve with any initial assumptions (because the equations are linear) al_nlegsolve.sm (12kb) downloaded 12 time(s).

Hi Martin. I use Maxima's ev() because SMath's Assign() only works with the variable names, instead others, like xo, yo, and SMath's at() doesn't works for the symbolic evaluation, as shown this picture: example_v1.sm (16kb) downloaded 5 time(s). This is a workaround for use only SMath native functions or plugins, without any explicit Maxima function: example_v2.sm (16kb) downloaded 6 time(s). Best regards. Alvaro.
