Question

Which of the following illustrates the use of the commutative property of addition?
(7x + 6y) + 3z = (6y + 7x) + 3z
(7x + 6y) + 3z = 7x + (6y + 3z)
(7x + 6y) + 3z = (7x + 6y) + 3z
(7x + 6y) + 3z = (7x + 6y + 3z)

Answer 1

(7x + 6y) + 3z = (7x + 6y + 3z)

Answer 2

( 7x + 6y ) + 3z = ( 6y + 7x ) + 3z Commutative property is when you switch the places of 2 things like 6y and 7x

Answer 3
