Thanks, Murray. Inspired by your example, I created a LyX example that actually works. The procedure is the following: 1. CONTROL + SHIFT + M; 2. Insert --> Math --> Delimiters; 3. Insert the unmatched bracket; 4. Insert -- > Math --> Aligned environment; 5. Insert the equations; 6. Insert the equivalence symbol; 7. Insert the second system of equations. An example file is attached. Paul
