I deed help with algebra
9 / m+7 =
16 / 19x =
I do not understand your question. What are you trying to do?
In mathematics, you don't understand things. You just get used to them.
Of course that result can be rigorously obtained, but who cares?
Combinatorics is Algebra and Algebra is Combinatorics.
If you want to solve for m and x (respectively), you'll have to tell us what the other side is equal to.
Also, is it 9/(m+7) or (9/m)+7?
