Silverlight 3 (on which the Windows Phone 7 framework is built) doesn't support MultiBinding, which is what you would use to achieve what you need. However, there is a workaround solution that you can use described in the post MultiBinding for Sivlerlight 3, which should also work on WP7.

Alternatively, you could extend your view model (or at least the properties that you are exposing) to expose a property that aggregates your values and raises property change notification when either changes.
