using ublas to solve linear systems?

I'm trying to see if I can use ublas to solve a linear system of equations.

Digging through the documentation, I find a description of a function
called 'solve" that says "Solves a linear equation for a triangular matrix."
There is also a formula,

B = solve(A, B, tag)   <------>      B <- A-1 B

But I just don't know what any of this means (even though I am a 
mathematician and quite fluent in linear algebra).

So
a) can ublas be used (without me implementing any additional
algorithms) to solve a linear system of equations?
b) what exactly does the function solve do?
