I just need help with part B, i'm pretty sure part A is useless but I found Req to be 5 ohm

2. Relevant equations

V=IR

3. The attempt at a solution

Well basically I found the voltage change going through the 5ohm to be 10v but then I don't understand how to find the current through anywhere else.
