Indicate which property is illustrated in Step 6.

Step 1 8 - 6x - 8 + 7x = (8 - 6x) + (-8 + 7x)
Step 2 = (8 - 6x) + (7x - 8)
Step 3 = 8 + (-6x + 7x) - 8
Step 4 = 8 + (-6 + 7)x - 8
Step 5 = 8 + x - 8
Step 6 = x + 8 - 8
Step 7 = x + 0
Step 8 = x

Question

Indicate which property is illustrated in Step 6.

Step 1	8 - 6x - 8 + 7x	=	(8 - 6x) + (-8 + 7x)
Step 2		=	(8 - 6x) + (7x - 8)
Step 3		=	8 + (-6x + 7x) - 8
Step 4		=	8 + (-6 + 7)x - 8
Step 5		=	8 + x - 8
Step 6		=	x + 8 - 8
Step 7		=	x + 0
Step 8		=	x

I believe this is identity property but I'm not sure

I think commutative   only rearranging the order 
a + b + c = b + a + c 
8 + x - 8 Step 6 = x + 8 - 8
