What this needs
Learn these first — this section will not make sense without them.
Nothing in the algebra book is a prerequisite for this section.
What this touches
Algebra that turns up here. Not a blocker, but this is where you will see it used.
Identifying an unknown product nuclide balances two independent one-step linear equations — 25 + 4 = A + 1 for mass number and 12 + 2 = Z + 1 for charge — each isolated exactly like solving for x; they are not a system needing elimination, just the same isolate-the-unknown move performed twice.
