## Homework Equations

v=ir

r1+r2 = r3

1/r1 + 1/r2 = 1/r3

v1 + v2 = v3 ?

## The Attempt at a Solution

im guessing this has something to do with simultaneous equations but im not sure about the extra battery. And which circuits am i supposed to pick, because i can see 4 different paths (2 for each battery) and am not sure if i need to have the battery's in different paths or not.

basically i'm very confused any help would be appreciated

thank you
