Question 1173903
<font size=6><b>Oh crap.  The other guy did it for you!!!!</b></font>

Instead of doing your problem for you,  I'll do one exactly like it that you
can use as a step-by-step model to solve yours by.  The one I'll do is:
</pre>
3m +  n = 0
 m + 3n = 16<pre>
Solve 3m + n = 0 for n
           n = -3m

Substitute (-3m) for n in

    m + 3n = 16
m + 3(-3m) = 16
    m - 9m = 16
       -8m = 16
         m = -2

Substitute -2 for m in
   
         n = -3m
         n = -3(-2)
         n = 6

Now do your problem exactly the same way.
