I am thinking the answer is
n = 7a - i
____
w
2007-03-31 06:57:52 · update #1
a = w(i + n)/7
7a = w(i + n)
(7a)/w = i + n
n = (7a)/w - i

a= wi+wn divided by 7..... times 7 .....7 a = 7wi+7wn ... 0 = 7 wi+ 7wn- 7a divided by n ... n = 7 wi + 7 w - 7a is ur answer! im almost positive

What's 7 have to do with anything?
Assuming that a=w(i+n), after distributing a=wi+wn. If you divide by 2w, you get a/2w=in. Now you have to divide by i, but you can't do this, so you multiply by one over i or 1/i. n=1/i times a/2w

isolate n on the right side.
first multiply both sides by 7..you get 7a = w(i + n)
then divide both sides by w, you do it....
then subtract i from both sides......
all that remains on the right side is n

ok, you need to start by getting rid of the denominator on the side where your variable is by multiplying by 7
7a=w(i+n)
now divide by w
7a/w=i+n
and subtract i
7a/w-i=n
and there's your value of n

w=5
n=7

a=(w(i+n))/7
7a = w(i+n)
7a = wi +wn
7a-wi = wn
(7a-wi)/w = n
