**Help generation**, Saturday, September 26, 2009 at 4:11pmNo I think the answer is m=d/n

check it out.

n=m+d, for m

first subtract m

n-m=d

then divide both side by n leaving m alone

m=d/n

**PsyDAG**, Sunday, September 27, 2009 at 2:34pmYou both made mistakes.

n=m+d, for m

Merely subtract d from both sides.

n - d = m

If you have n - m = d, to get m alone you need to subtract (not divide) n from both sides.

-m = d - n

Multiplying both sides by -1 gives you

m = - d + n = n - d

I hope this helps. Thanks for asking.
