i better do math than talk in english.

D:=42

C:=5

C:=(D-d)/L

(yes, can be done even mentally, but how you do it in mathcad?)

It is helpful to know which version of Mathcad you are using.

If you want to solve to "d" then look at using symbolic math (in help). The := or definition operator should not be used here but use the evaluation operator (displayed as a bold =). Then you can solve for "d". Again, looking at symbolic examples in help should help you along...

I hope this helps.

Or you could do it purely numerically, by using the root function with C-(D-d)/L as the first argument.
