Need help with simple math problem - Taem - 08-31-2013
N = R + ( (R/3) * (P/2) )
I want to move P to N ='s place and N somewhere inside the formula.
How do I do this? I'm doing a formula in Excel and need to figure out something backwards. I'm sure the answer is beyond simple, but the arithmetic escapes me atm.

I want to move P to N ='s place and N somewhere inside the formula.
For R not equal to zero:
N = R + ( (R/3) * (P/2) )
R + ( (R/3) * (P/2) ) = N
(R/3) * (P/2) = N - R
P/2 = (3/R) * (N - R)
P = (6/R) * (N - R)
P = (6N/R) - 6
Hopefully I haven't made any goofs. Algebra 1 was a long time ago.

The answer is 2.
