Hi folks, looks like this isn't such a newbie question after all.
Maybe I should ask it more carefully. I want to use LyX to produce systems of equations that look like this (output exported from LyX): $\left\{ \begin{array}{rrrrr} (3-\lambda)C & + & 2D & = & 0\\ C & + & (4-\lambda)D & = & 0\end{array}\right.$ but with each line numbered, like eqnarray Reasons are that I want the operators to line up correctly, and it will match the course textbooks that I am using with an Open University Maths course that I'm doing (they were published using TeX). I've tried all kinds of combinations of brackets and environments with no luck. By the way, the user guide says this in section 5.2: "If you decide after the fact to place parentheses (or other math structure, like a square root, or other decoration) around some math structure, you can do that by highlighting (selecting) the structure that is to go inside the parentheses...Then, choose the appropriate brackets for left and right, and click on Apply. The parentheses will be drawn around the selected structure." This does not appear to be true for equation environments or arrays for that matter. Has this been done in LyX yet?
