How to preserve a constant when doing symbolic solve?

Dear friends,

Is there any possibility to tell Mathcad Prime 2.0 to display constants with their symbols (in contrast to evaluating them) when performing a symbolic solve of a function?

P.S. The constants are defined by the user.

Mathcad Prime 2.0, has a clear( ) function to clear variables for re-use further down the sheet.

Also the clear.sym( ) function allows you clear said variables for use in symbolic applications whilst retaining numeric values.

see example below.

Thank you.

Why the formula is becoming grey after using clear()? (see my attached example).

I used clear_sym() also in other projects an most subsequent equations turned grey. Is this normal?

What is the opposite to clear_sym()? (to make evaluating of variable possible again in symbolic solve).

Answer: There is no opposite...see explanation in screen shot
