Source transformation

    1. The problem statement, all variables and given/known data
    I am a bit confused on why they can just randomly short the 4kΩ resistor, as you can see from the first pic to the second pic.

    They didn't just short the 4K resistor. The 5 ma current source, the 16K resistor and the 4 k resistor was made into a norton (or is it thevinin) equivalent.

    It's Thevinin, I just checked.
