Answer:
<h2>-5 + 7x</h2>
Step-by-step explanation:
The Commutative Property states that the order of addition or multiplication does not matter.
EXAMPLE 1 : 1 + 2 = 2 + 1 = 3
EXAMPLE 2: 3 x 4 = 4 x 3 = 12
It appears that we cannot use the commutative property on this expression. But we can. First, we need to change - 5 = + -5.
7x - 5 = 7x + -5
Because we now have addition, we can prove the commutative property.
-5 + 7x = 7x + -5
I'm always happy to help :)
