Answer:
A) Commutative
Step-by-step explanation:
The Associative has to do with re-grouping numbers. There are only two numbers so this does not apply here. Commutative is where you change the order; that's what the equation is demonstrating.
Let’s make
P = Pamela
J = Jiri
J - 6 = P
P + J = 78
We can replace P with J - 6 because they are the same thing.
J - 6 + J = 78
2J - 6 = 78
2J = 84
J = 42
Jiri is 42 years old.
