Aligning height-differing equation lines in tabularx

I have the following array of equations produced by tabularx, in which I want the rows in the left and right panels to be aligned such that they look like they're written on the same line of binder paper, for example. But since the equations are apparently aligned at the very top, the tall summand symbols in the right panel lead to the following aesthetic horror:
How can I fix the alignment? A MWE appears below.

As I don't understand why you use a tabularx environment for your equations, except perhaps to have the whole alignment near the left margin, I propose this very simple solution with alignat2, which displays two columns of alignment, with a controllable space between them. To have them near the leftmargin, I used the fleqn environment from nccmath (remove it if you want the equations be centred), and added some improvements from mathtools. In particular, coloneqq which provides a :=, with the colon centred on the maths axis, and vertical dots centred w.r.t. :=:

A quick fix using vphantom.
This creates a 'phantom' zero width box with a vertical height equal to the size of sum_j=3^C.
