Indicate which property is illustrated in Step 8.

Step 1 11 - 6x - 11 + 7x = (11 - 6x) + (-11 + 7x)
Step 2 = (11 - 6x) + (7x - 11)
Step 3 = 11 + (-6x + 7x) - 11
Step 4 = 11 + (-6 + 7)x - 11
Step 5 = 11 + x - 11
Step 6 = x + 11 - 11
Step 7 = x + 0
Step 8 = x

Question

Indicate which property is illustrated in Step 8.

Step 1	11 - 6x - 11 + 7x	=	(11 - 6x) + (-11 + 7x)
Step 2		=	(11 - 6x) + (7x - 11)
Step 3		=	11 + (-6x + 7x) - 11
Step 4		=	11 + (-6 + 7)x - 11
Step 5		=	11 + x - 11
Step 6		=	x + 11 - 11
Step 7		=	x + 0
Step 8		=	x
