The property demonstrated is: <u>Associative Property of Addition</u>.
Step-by-step explanation:
We need to identify which property is demonstrated in the equation: ![(2+x)+3y = 3y+(2+x)](https://tex.z-dn.net/?f=%282%2Bx%29%2B3y%20%3D%203y%2B%282%2Bx%29)
The property demonstrated is: <u>Associative Property of Addition</u>.
Reason:
Associative property states that the numbers can be added irrespective of how the numbers are grouped.
The associative property of addition states that:
(a+b)+c=a+(b+c)
Same property is used in the given equation: ![(2+x)+3y = 3y+(2+x)](https://tex.z-dn.net/?f=%282%2Bx%29%2B3y%20%3D%203y%2B%282%2Bx%29)
