Answer:

m=18

Explanation:

The equation given is
D=(m)/(v)

and also we have that
D=(6)/(7) , thus:

(6)/(7)=(m)/(v)

------------

I think the question is missing which variable is defined as
=m+3 , so I will solve for
v=m+3 since is the only other variable in the equation.

substituting
v=m+3 into
(6)/(7)=(m)/(v) :

(6)/(7)=(m)/(m+3)

and we solve for m:

$(m+3)(6)=7m\\6m+18=7m\\18=7m-6m\\18=m$

m is equal to 18.
