How to find R in L=MR/P+RS?

Question

How to find R in L=MR/P+RS?

Answer 1

R=L/(M/P + S)

Answer 2

L=MR/(P+RS)

L(P+RS) = MR

LP + LRS = MR

LP = MR - LRS

LP = R(M-LS)

LP/(M-LS) = R

Answer 3

L = MR/(P + RS)

LP + LRS = MR

LRS - MR = - LP

R(LS - M) = - LP

R = - LP/(LS - M)

Answer: R = - LP/(LS - M)

Answer 4

PL + RSL= MR

PL = MR - RSL

PL = R ( M - SL)

R= PL / ( M- SL)

ANSWER

or, if the equation is L= (MR/P) + RS

L=R ( M/P + S)

R=L/(M/P + S)

ANSWER

Answer 5

I don`t trust this type of question because, as typed, it could mean :-

(i)  l = (MR/P) + RS

or

(ii) I = MR / (P + RS)

(i)

I - RS = MR / P

P I - RSP = MR

PI = RSP + MR

PI = R (SP + M)

R = PI / (SP + M)

(ii)

L (P + RS) = MR

LP  + LRS = MR

LP = MR - LRS

LP = R (M - LS)

R = LP / (M - LS)

Answer 6

L=MR/P+RS

L-RS=MR/P

P(L-RS)=MR

PL/M-R/M(SP/M)=R

PL/M-SP/M=2R

(PL/M-SP/M)/2=R

just a guess cuz i have no idea
