A+b=32
a-b=8
let's subtract bottom equation from the top:
a+b-(a-b)=32-8
2b=24
b=12
Then a=20
Answer:
The commutative property of multiplication states that the numbers of the operation can change their order, and this action will not alter the outcome.
Example 1:

Changing the order of the numbers in the operation:

Example 2:
