entering different estimates. The closer you can estimate the answer,
the more likely that the Solver will find a solution.
Case 4: The calculator displays:
The Solver is unable to find a solution. Check your equation to make
sure you have made no errors in entering it. Also check the value of
each known variable. If your equation and variables are correct, you
might be able to find a solution by entering very good guesses.
