Although not common, most model codes will allow you to connect two lavatory sinks with a continuous end-outlet waste, much like used under a kitchen sink.

As long as the service stops are accessable, then you don't need to run piping in the wall seperately for each sink. You can tee off of the one sink.

If you do use a continuous waste, then only one trap would be installed, if you use a wye, then each sink would need to be properly trapped.

Both these sinks will be in the same cabinet?

What if they arent in the same cabinet and they are two sinks back to back separated by a wall, but are within 30"? Can they still be tied together only using one trap?
