Find inductor current for t > 0

Switch is initially open and closes at t=0+

The professor wants us to solve these only using the Diff Eq approach. On other questions I would just do a KVL with the inductor loop and solves the resultant ODE. However with this one I would have to do a system of equations. I'm not to sure if thats what I'm supposed to do or even how to do that math.

I also tried taking the inductor out and doing a thevenin equivalent. I get the correct time constant this way but the constants of integration are way off.

I really just dont know how to approach this problem.

fyi I'm told the answer is 6 - e^(-t/6) A,

whoops sorry for the typo in title, been a tiring day.
