- We solve a symmetric equation with strict domain checking ON. To bring the
- equation to a form in which we can see how to use substitution, we have to
- divide by a variable, and that changes the domain. For this reason we must
- break down the problem into cases is check what happens when the variable is
- zero. This is done after pressing ENTER for the first time.
-
- Case 2 presents no difficulty - it is a contradiction.
-
- Case 1 can now be solved like Examp17.bib. We suggest you try to solve it
- yourself.
