 Question 43240: 1/R= 1/R1 + 1/R2 SOLVE THE EQUATION FOR R1 IN TERMS OF R AND R2. i KNOW the first step is to isolate 1/r1 1/r-1/r2=1/r1 my guess is r1= (r-r2)/r*r2Found 2 solutions by fractalier, psbhowmick:Answer by fractalier(2101)   (Show Source): You can put this solution on YOUR website!Actually the best first step is to clear all fractions by multiplying by the lowest common denominator...here that is r*r1*r2...so we get 1/r = 1/r1 + 1/r2 r*r1*r2[1/r = 1/r1 + 1/r2] r1*r2 = r*r2 + r*r1 then collect terms with r1 and solve r1*r2 - r*r1 = r*r2 r1(r2 - r) = r*r2 and finally r1 = r*r2 / (r2 - r) Answer by psbhowmick(529)   (Show Source): You can put this solution on YOUR website!Yes the first step is correct.
