I'm not in High School but I figure the question is around this level so I'll post it here.
Essentially I'm trying to post this formula in excel, so I need to solve x, or have it so I can plug in the variables I know and get the result.
The forumla currently is
S = D - X / CX + 1.5V
S, D, C, V are all known.
Any help here would be appreciated. If you need any more information again please let me know.
