I compared LibreOffice and OpenOffice:
Save as .doc yes yes
Equation saved as MTEF, editable OOmath, not editable
Roundtrip no, stays MTEF remains OOMath
MTEF remains MTEF
Save as .docx yes no
Equation saved as OMML, editable
Roundtrip yes, back to OOMath
MTEF remains MTEF
Abbreviations:
OOMath = OpenOffice or LibreOffice Equation
MTEF = Microsoft Equation Editor (up to Word 2003) or MathType
OMML = Microsoft Equation (Word 2007 and up)
So, roundtrip is best with
LibreOffice saving as .docx and opening from .docx
