As the title states I am trying to solve 4 equations simultaneously for unknowns.

 

I would like to solve for SM, KM, and RM. 

 

I tired all sorts of things and now here I am, admitting I need help.

Thank you very much, this is what I am looking to do.

 

I still need help, I get stuck trying to input four variables to symbolically solve for.

It helps to NOT define your known constants numerically BEFORE you do symbolic operations. As an alternative you might use the clearsym function (look that up in the help!).

But most of all: DO attach your worksheet, NOT only a picture.

You should be able to do this in Prime:

(I can't because I'm limited to Prime Express).

 

Success!

    You have to type "solve, DeltaT,...." in the placeholder above of the arrow similar to what you see in the picture provided by Luc. Lucs picture is from real Mathcad but this also works in Prime.

    In case you still have problems getting the answer you should consider posting your worksheet instead of just a picture.
