The Attempt at a Solution
I am struggling to begin with this one.
I can think of tons of different ways to begin, but all seem to get into a hazy area where I am unsure.
I could start by adding or "subtracting" from both sides λ|v> or by adding 0 to both sides, or any other traditional proof ways.
Is there any hint to help me go in the right direction?
