Just a quick question trying to re-arrange a formula.
How do we do it when the subject we want is on both the top and the bottom in a fraction? An example would be something like the following.
Make R the subject.
or something similar.
Any help is appreciated.
yeah, I can get that far.
From there you could divide by M which would result in R being on it's own on one side, but how do you get rid of the other R (part of NR)? That's the part I couldn't get. Typically to break it up you divide by N but then we're going backwards making the R which was on it's own
