$(p or q) xor (p and r) => (p xor) xor (p xor r)$

What are the truth values of p, q, r that make LHS T?

$p or q$ | T $p and r$| F

p	q	r	RHS
T	T	F	F xor T = T
T	F	F	T xor F = T
F	T	T	T xor F = T
F	T	F	T xor T = T

This logical implication is invoked by

1. p | F
2. q | T
3. r | F

$(p xor q) xor (q xor r) => (p or q) xor (p and r)$

What makes LHS T?

$(p xor q) xor (q xor r)$ | T

1. $p xor q$ | T $q xor r$ | F
2. $p xor q$ | F $q xor r$ | T
