The classic solution to this problem is to put the equation in the middle cell of a three-column, one-row, borderless table. Other elements can then be entered in the left and right columns, with paragraph alignment and Spacing Before/After adjusted as needed.
It's not just the classic solution, it's the only solution when anything has to appear on the same line to the left of the "display" equation. It's based on the fact that the text in each cell of a table is in a separate paragraph from the other cells.
Word's internal (and not modifiable) programming says that any equation that's in the same paragraph with non-equation text must be displayed as "inline".
