can someone please check my answer to this problem?
solve for indicated letter.
n=m+d, for m
the solution is m= (n+d)/m
is this correct?

No I think the answer is m=d/n
check it out.
n=m+d, for m
first subtract m
nm=d
then divide both side by n leaving m alone
m=d/n

You 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.
