Indicate which property is illustrated in Step 3.

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

A- identity
B- associative
C- commutative
D-distributive

Question

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

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