V=12R/(r+R) solve for R

• V=12R/(r+R)
  => V*r + V*R = 12R
  => Vr = 12R - VR
  => Vr = R(12-V)
  => R = Vr/(12-V)[V is not equal to 12]

• v(r+R)=12R
  vr+vR=12R;(12-v)R=vr;

• V=12R/(r+R)
  
  => (r+R)/R = 12/V
  
  => (r+R)+1 = 12/V
  
  => r/R = (12/V)-1
  
  => r/R = (12-V)/V
  
  => R = Vr/(12-V)
