It's sounds like you can tee them into one drain according to Tony but I was told you also need to run another vent from the new sink and tie that in a certain way as well. Was told if you just tee into the same drain pipe then draining one sink can end up siphoning the other sinks pee trap. Unless you can run a single pee trap but I was never given this option.
