I=E/(R+r)

multiply both sides of the equations by (R+r):

I(R+r)=E

divide both sides of the equation by I:

(R+r)=E/I

subtract r from both sides of the equation:

R=(E/I) - r

*Note: lol wise guy..you were still right in your first answer..it still came out the same. But follow my lead of course :)

multiply both sides by (R+r)

I(R+r) = E

divide by I

R+r = E/I

subtract r

R = E/I - r

Yeah, but I added a lot of unnecessary steps, I was just having a brainfart, so I made it simpler
