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.
