7.3Systems of Linear Equations: Three Variables

What leans on this
Chemistry that uses this algebra — the answer to why you are learning it.
A harder balance — three or more independent coefficients constrained by one atom-balance equation per element — is a genuine 3-variable (or larger) linear system underneath the inspection method; seeing the chemistry first gives the algebra's abstract three-unknowns problems a reason to exist.
