hello im solving the equation at the end .But i dont want that unknown variable to be marked in red colour how to solve this problem.

Best answer by MikeArmstrong

Or you could just define as T_2_10k like in the attached.

You could make make the formulas dependant on the unknown parameters functions.

Please provide a worksheet if you are unsure.

Is there a reason you are solving this symbolically?

If the equations you show are just for reference and are not meant of defining variables, you can use the boolean equal sign instead of the assignment :=. That way you would use Mathcad as a simple equation editor.

Here is another approach using a solve block to solve for all six unknowns simultaneously. The benefit is, that after the calculation of T_2_10k we do not need to call function or redefine variables a second time to get the other variables like tau_2_10k or sigma1_2_10k.

Certainly the most elegant way
