Concepts

A one-variable equation like $40 + 25m = 215$ finds a specific value
of $m$ . How is a two-variable equation like $C = 25m + 40$ different?

It has no solutions because two unknowns cannot be solved.

It describes a relationship with infinitely many $(m, C)$ pairs
that satisfy the equation.

It is the same as the one-variable equation but uses a different
letter.

It can only be solved when specific values of $C$ are given.
