Question

Indicate which property is illustrated in Step 6.

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

distributive
identity
commutative
associative

Answer 2

I believe this is identity property but I'm not sure

Answer 3

I think commutative only rearranging the order
a + b + c = b + a + c
8 + x - 8 Step 6 = x + 8 - 8
