Hi, not a homework problem as such, but I am studying introductory quantum physics and having some trouble understanding how applying the rising or lowering operator for angular momentum implies:

Regarding the answer to that post, I can get to the two expressions quite easily by using the commutation relations, but even after reading it multiple times, I don't understand how the proportionality is implied. I know this is probably trivial and I'm probably just missing some obvious fact due to the time being 1.30am. Any help would be greatly appreciated.
L+/-|l,m> ∝ |l, m+/-1>
Basically, my question is the same as the first part (Q1) as described in the following link.
