I realize that much of the value of Mathematica 8 is in its automatic algebra. However, if, e.g., in a textbook, I want to follow someone's work, it would be helpful to be able to do simple algebra to an equation. E.g.:

x(y+7)/x^2==x y

Now, what would be nice is to have a function that does the same thing to both sides, something like "BothSides[%/x]" to give

(y+7)/x^2==y

*without* automatic simplification. This example is really too simple, but it shows the point. BTW:

{x(y+7)/x^2,x y}

*almost* works with %/.someruleoranother, but it is very limited in how much algebra it will do to to "see" the rule and apply it.

Or is there already a way to do this and I am too blind to see it?

Many thanks.
