- The solution of the simultaneous equations in the Equations window is complete.
- All that remains is to press the Answer key.
-
- By clicking on the tabs at the top we can see all the transformations we
- have carried out so far. In this problem there are eight of them.
- Because not all the tabs fit in the window, you have to scroll from time
- to time by clicking on the arrows on a level with the tabs.
-
- Transformations can be performed only in the lower half of the window.
- Operations on both sides can be marked only in the upper half of the window.
-
- If you wish, you can open a new Equations window and try to solve this
- example yourself. You can do this in any way you choose.
