Alignment when placing equations side by side in multipage environment

Question

I have a question concering the alignment of multiple equations that are placed on one line. An earlier topic described a few methods that can be used. (side-by-side equations, with equation numbers for each)

In my report I have used the multipage-approach, but I can't get the equation numbers to align vertically. I have also tried the tabularx-approach, but in that case the vertical alignment of the equations themselves is completely messed up.

Below is a MWE. I find the vertical alignment with multipage to be just fine, using the set of usepackages provided at the bottom of my post.

For the equations, I would like the vertical centers to be aligned. For the equation numbers, they should be on the same vertical line throughout the document, at the end of my textwidth or linewidth.

Does anyone know how to get all the equations aligned properly? Thanks for your help.
