[HELP] How do I make one door open two doors?

Hello! I've tried googling the question but I couldn't quite find what I wanted. I've got a wall mounted cabinet like this and I'm turning into an art project of sorts. What I'm trying to do is, when you open it by pulling the right hand door open, the left hand door opens in tandem.

I've got string. I've got hooks. I just can't figure out how to do it.
