Both the equations are the same!
a) When N=27, R=96/12 = 8.
b) When R=42, N= 8*42/3 - 5 = 112-5 = 107.
c) When N=0, R= 15/8

i have a couple of question for people of they are willing to help me please,
1) the equations connecting the running cost of a piece of apparatus,R,and the number of times it is used in one month,N, are
R=(3N + 15)
----------
8
and
N= 8R
----- - 5
3
use these equations to calculate
a) the value of R when N=27
b) the value of N when R= 42
c) the value of R when N=0
this is really getting to me please help thanks to anyone who can
