i don't even know if i did it right

I didn't check through all your algebra, but you did set it up right: all of the equations for the net forces are correct, so it's just a matter of algebraically solving them.

I agree with Ambitwistor: you set up the force equations for each body correctly. The equation for the first body is solved correctly (T1= 78N). But I don't see how you went on to solve for μ and T2. I suspect an error there.
