Indicate which property is illustrated in Step 6.

Step 1 8 + 12x - 8 - 2x + 2 = 8 + (12x - 8) - 2x + 2
Step 2 = 8 + (-8 + 12x) - 2x + 2
Step 3 = [8 + (-8)] + (12x - 2x) + 2
Step 4 = 0 + (12x - 2x) + 2
Step 5 = (12x - 2x) + 2

Question

Indicate which property is illustrated in Step 6.

Step 1	8 + 12x - 8 - 2x + 2	=	8 + (12x - 8) - 2x + 2
Step 2		=	8 + (-8 + 12x) - 2x + 2
Step 3		=	[8 + (-8)] + (12x - 2x) + 2
Step 4		=	0 + (12x - 2x) + 2
Step 5		=	(12x - 2x) + 2
Step 6		=	(12 - 2)x + 2
Step 7		=	10x + 2
