HP Prime: Isolate a variable in an equation
Hello friends:
How to isolate a variable in an equation on HP Prime? Can anyone guide us? Searched the Guide and not found. Thank You David

I'm not an expert but I tend to use the solve() command in CAS mode. For example
Solve(x+y=4,y) should return 4x. Good luck.

In CAS view, solve() should be of help.
E.g., solve(x^24*y*x=3,y) returns {(x^2+3)/(4*x)} Or solve(x^24*y*x=3,x) returns {2*y+sqrt(4*y^2+3)} Is that what you are after?

But, using this command with different variables X and Y, appears a recommendation that doesn't work either. Another observation is that the result is not symbolic when the variables are different from X and Y. Grateful David

You need to type in lower case variables.
