If you divide both sides of the equation by 7, you will get the value of b.  This uses the division property of equality.

If one were to look at this equation carefully, the equation could be reworded in a different but similar scenario:
 
a(b)=(b)a where a(b) is just the inverse of (b)a (Commutative Property of Multiplication)
 
Similarly, if a=7 then you get the scenario from the given equation:
 
7(b)=(b)7=12(7).

 It is trivial really divide both sides of equation by 7.
