Indicate which property is illustrated in Step 6.

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

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

commutative law maybe?

anonymous · Answer

$$a+b=b+a$$so 
$$3+x-3=3-3+x$$

Yeah, that makes the most sense I guess. :)
