7m + 12
We've examined it carefully looking for an 'equals' sign ( = ), but we've been
totally unsuccessful. So we know that it can't be an equation.
It must be an expression.

You cannot.!!!! Because it is an Algebraic Expression NOT an Algebraic Equation; there is NO 'EQUALS (=)' sign.
It is a linear equation in the single variable, m. It has the solution m = 0
3m + 7m + 1 = 10m + 1
-7m - 3m + 5m = -5m
If 7m = 4n+2 and 7m+2 = 8 m = 6/7 and n = 1
