Different systems playing same music simultaneously


I have four different systems located in different rooms.
Is there a way to make them play the same music like a multi-room system?
Could I send the signal from one source to all the systems at the same time?
Each system has its own amplifier and speakers.
Is bluetooth an option? Can I use a transmitter and several receivers?
Does anyone have this kind of setup?

Real crying shame Google ceased production of the Chromecast Audio puck.
Great little device.
I have two of them on two different systems and control them from either Google Home or bubble UPnP on my droid phone.
No issues at all.
They see Qobuz, tidal, Spotify and my nas on the PC.
Not bad for $40 a pop of Fleabay.
Depend on setup.
If all analog signals means running lots of long runs of cables and a multi out box, can be done but it's work.
Networking as Audiotroy states is better option.
But all depends what you have in your systems.
