Databases - Normalizing relations

[binaryperson]

Hello. Can someone please explain step by step how to normalize the following relation.

Relation: R(ABCDEFG)
Functional dependencies: F = {ABC -> DEFG, AB -> DFG, B -> EF}
Assumed primary key: A (I'm not sure what is meant by this.)

Please find the first(By expanding the primary key), second, and third normal forms. Please explain as much as possible.

I genuinely want to learn how to solve these kinds of problems. Don't tell me you won't do my homework; IT IS NOT HOMEWORK. You either believe me and help me or don't help me and I don't learn.
