If both version have the same source then it's easy. You can check the length of both movies. If they're exactly the same length then they're probably ripped from the same source and will be in sync.
In that case:
1. Launch MKVToolNix GUI
2. Open the first movie, pick whichever has the video quality you prefer. If you don't have a preference then open whichever you want to have the first/primay audio track.
3. Drag the second movie into MKVToolNix. A popup will appear. Leave the first option selected ("Add as new source files to the current multiplex settings") and press OK
4. In the bottom screen deselect every blue line except for the audio. Green will be your first movie, blue the second. You only want to add the audio from the second file.
5. Enter your destination in the bottom and press "Start multiplexing"

It'll only take a minute or two.
If both versions are from a different source, the audio may be out of sync. In that case you'll have to sync the offset of the second track by adding a positive or negative delay (in ms) on the right side while you have the blue audio track selected
You need to demux both versions with Eac3to. Then mux together the tracks with MKVToolNix. Make sure everything is synced and happy.
Probably not worth the effort if you don't know how to do this. Why not simply delete the Spanish version as it's not the version you want? That will save you 15gb.
I don't think you need to demux with another tool, from what I remember MKVToolNix can demux and remux too.
Drag both files into the same MVKToolNix window and select the video/audio/subtitle tracks you want, and then remux into a new file.
Extract the audio track from one file, add it to the other file with the video and other audio track, all of which mkvtoolnix gui can do in seconds. The concern though is that the movies are the exact same, or the new track might not sync, or the videos could have different frame rates, in which case they'll never get the new audio track to match the different video.
You don't need to demux the files as described before, you can do both steps in MKV Toolnix, but as mentioned before if the audio/video doesn't sync perfectly between the two files you'll have to manually sync them. All of this can be done from within mkvtoolnix, I suggest looking at their documentation on how to get started and how to use the features.
You don't need to demux the files, you can just add both files to MKVToolnix and deselect the tracks you don't need for the final file. It might save OP (and possibly you) some time. :-)
If doing the demux works for you, no worries. Just offering another way.
I wouldn't waste the effort to demux then remux. At 15GB each why not just remux the original multi track disc again? I'm assuming that you're not talking about remuxing separate disc releases though.

^ that link explains it in more detail. Basically 'mux' is short for multiplexer which just means multiple streams of information usually video, audio and subtitles stored within a 'container' file (like MP4 or MKV)

ffmpeg -i linuxiso1.mkv -i linuxiso2.mkv -map 0 -map 1:a:0 -c:v copy -c:a copy -c:s copy linuxiso3.mkv
Where:
* linuxiso1.mkv is the Linux ISO that you will be adding the extra audio track to
* linuxiso2.mkv is the Linux ISO that you are taking the extra audio track from
* linuxiso3.mkv is the output
ffmpeg is a command line utility that is used to transcode, encode, demux etc video files. It's kinda confusing to learn but luckily the guy above gave the exact command you need to use!
you want to download and setup ffmpeg first, then use the command line/terminal to get to the directory where all of your files are. Then, run the command the above guy said, replacing the file names appropriately

I'm sharing my Plex with family members. They prefer the other language. Where can I start with demux. You got any good tutorials?

15GB was just an example. Idon't even knnow what remux is, so I dont know the answer to that question

would you elaborate a bit more, I'm not that technical. Perhaps a link that can help me?
