Can somebody give me steps on how to go about doing formula rearrangement? (algebra)

As a general guideline, I would cluster the variables and
numbers into "terms" by following rules of the four
operations.

Manipulation of variables, making a variable
the subject, is a matter of systematically carrying out a series of negating operations
on both sides of the equation, again obeying rules of the four
operations.

Will require you to supply examples, questions
on Algebra which you stumble upon, so that I can demonstrate what I meant in the
preceding two paragraphs.
