Hi,

 

I am a new user and I would like to know if there is any way to perform the attached simple equation dividing.

I need the unknowns to appear as they are in the K equation

As Terry already wrote you need to use the symbolic evaluation if you want a symbolic result.

If if you are confused by the red errors (which stem from the numeric engine as of the undefined variables) you can define appropriate functions.

This has the additional advantage that you can evaluate them not only symbolically, but also numerically if you provide numerical input values.

Prime 9 sheet attached

 

BTW, its always a good idea to attach your worksheet (even if it contains just a few lines)  along with the pic if you have a question and in in case of Prime its also beneficial to state the version you are using.
