terminal voltage and current flow

1. The problem statement, all variables and given/known data

(a) Calculate the magnitude and indicate the direction of flow of current in Figure 20.40. E2 = 19.0 V and r2 = 0.55 Ω.

(b) Find the terminal voltage of each battery.

2. Relevant equations

V = Ir

3. The attempt at a solution

I found the answer for part a to be 4.52 but i don’t know how to get the second one.
