Me and my daughter are stuck rearranging this formula,her notes from class aren't that clear and it's 35yr since I was at school, please help,
X=p-q
pq
i.e. p-q divded by pq = x
where q needs to be the subject
We've taken it as far as xpq =p-q but are now struggling.
Many thanks Mark

They show how to type math here. Yours would look like "x = (p - q)/(pq)". (I'm assuming that "X" and "x" are supposed to be the same thing??)

They show the trick for this here. Yours would like like:
xpq = p - q
xpq + q = p
(xp + 1)q = p
Finish.
