This work sheet is under construction. It is expected to be around 50 pages. Here is a very minute fraction of the skill and difficulties to use the solver Given/Find. What I'm pointing to is the image ... lot of times you will have a plot but no export ! In previous versions of Mathcad, the examples from the qs hardly hinted the power and versatility of this solver.
Hope it does not turn red in your version. The scripted component is the slider.
Audrey, convert the equation into a cubic polynomial, then simply use polyroot to find all the roots. The solution is the maximum of the roots-vector as shown in my solution.

The solution of your problem is that of root-finding. Therefore,any attempt to solve it any other way other than plotting the function crossing the x-axis is less than ideal.

Setting TOL 15 will be no different than any other method because they are all internally based on root.
