Question: Subtitution/explicit calculation


I guess the best way if i give an example, what i would like to achive with maple:


I want to get the underlined part essentially, because im creating calculations in standard report format, with a lot of variables and constants so i cant recall all of the variables before using them, but i have to create a verifiable calculation.
Please let me know if maple capable of this or not. (sorry if its already discussed, i didnt find any similar topic)


Please Wait...
