[CAS] (With CAS setup Simplify setting to Maximum)

solve(r = ((9/4)*p+25),p) ==> {(4*r-100)/9}

Note: Used lower case variables here, Upper case variables are reserved.

You can also use the uppercase vars, but they have to be inside single quotes. Just be careful if you evaluate the expression, the calculator will use the stored values.

simplify(solve('R' = ((9/4)*'P'+25),'P')) ==> {(4*R-100)/9}

I get "Bad argument value" when i input your solution

Just make sure you work in CAS "environment" and use lowercase letters in the equation Wink

Also double-check your writing.
