Do you know how it is possible to add 4 equations?

Just type the three equations and then, while still in the box for the last equation, press the Enter key. A new dottedborder box appears below. Works both on Word 2007 and on Word 2010. 


In the Office 2010 version of the equation editor, after inserting a brace, with it selected, I can just rightclick on one of its places and chose "Insert Equation Before" or "Insert Equation After". If you find it a bit tricky to hit the little boxes with the Ibeam, you may be able to do it with the keyboard: move the cursor around with the arrow keys and then use the menu key (generally between the right alt and ctrl on US Windows keyboards) to get the context menu for the item under the cursor.
