[SciPy-User] How to solve a single linear equation

[bert wiley]

Hello
   Ive just started using scipy and im learning some algebra. Ive read the
scipy tutorial and noticed they have an example of solving linear equations
and it uses 3 of them and takes a matrice for the params and one for the
constants. How do solve for a single linear equation like this  x+3y+5z =
10  ?   ive tried it like this

A = mat('[1 3 5')
b = mat('[10]')
linalg.solve(A,b)

but i get
raise ValueError, 'expected square matrix'

thanks
