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 4-x.

Good luck.

Solve(x+y=4,y) should return 4-x.

Good luck.

In CAS view, solve() should be of help.

E.g., solve(x^2-4*y*x=3,y) returns {(-x^2+3)/(4*x)}

Or solve(x^2-4*y*x=3,x) returns {2*y+-sqrt(4*y^2+3)}

Is that what you are after?

Thanks friends:

That's what I need. 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.

You need to type in lower case variables.
