Indicate which property is illustrated in Step 5.

Step 1 11 + 12x - 11 - 3x + 5 = 11 + (12x - 11) - 3x + 5
Step 2 = 11 + (-11 + 12x) - 3x + 5
Step 3 = [11 + (-11)] + (12x - 3x) + 5
Step 4 = 0 + (12x - 3x) + 5
Step 5 = (12x - 3x) + 5
Step 6 = (12 - 3)x + 5
Step 7 = 9x + 5

Question

Indicate which property is illustrated in Step 5.

Step 1	11 + 12x - 11 - 3x + 5	=	11 + (12x - 11) - 3x + 5
Step 2		=	11 + (-11 + 12x) - 3x + 5
Step 3		=	[11 + (-11)] + (12x - 3x) + 5
Step 4		=	0 + (12x - 3x) + 5
Step 5		=	(12x - 3x) + 5
Step 6		=	(12 - 3)x + 5
Step 7		=	9x + 5
