Not getting in any competition, but if u r referring to Elliptic Curve equations, or Schnorr signature, or something like that then your question should contain more details for ur audience something is missing here
I could say simply the 2EQs are mod different numbers, someone else said if the values are zero
However, both are not "Bitcoin related" so I'm just guessing u meant some associative properties of Bitcoin Cryptographic Algorithms

If we're talking maths, we can't leave out stuff and assume the other person guesses what we actually want to compute.
I would agree, that his question lacks a ton of information.

What are s1, k1, r1, x1 and z1? Natural numbers? Numbers on a curve? If so which curve? Which number is which coordinate?
And stuff like this..

Maths must be exact, that's what it's made for..
