flalign numbering

Question

I have an equation that is so large that it needs to span over several lines. However I also have a particular alignment that I want, so I used the flalign environment to lay it out as I want it to be. However, I end up with each line being numbered, when I only want one number for the whole equation:

    \begin{flalign} \label{soundness:goal}
    &   \gamma \tdash \{p\}\cmd\{q\} \implies \forall \sigma \in \TStore. \; \forall h \in \THeap. \; \forall \rho. \\
    &   \quad (\sigma, h) \vDash_{\rho} p \implies \forall t \in Trace_{\gamma}(\state{\cmd}{[\sigma]}{ h}). \; \exists n \in \mathbb{N}. \; length(t) < n
    \end{flalign}

Is there anyway that I can have an flalgn environment or similar, but only have the last line numbered?

Add \nonumber or \notag for the lines you want unnumbered. — Gonzalo Medina, Apr 19 '14 at 03:04
@GonzaloMedina Thanks, that worked perfectly! Can you add this as an answer so I can accept it? — Julian Sutherland, Apr 19 '14 at 03:06
@PaulGessler: Thanks! Already a member of other SX communities though, so I know the ropes :) — Julian Sutherland, Apr 19 '14 at 03:07

Add \nonumber or \notag for the lines you want unnumbered. By the way, are you sure flalign is the best option? I ask because this environment is rarely used.
