Question

Indicate which property is illustrated in Step 3.

Step 1 10 - 6x - 10 + 7x = (10 - 6x) + (-10 + 7x)
Step 2 = (10 - 6x) + (7x - 10)
Step 3 = 10 + (-6x + 7x) - 10
Step 4 = 10 + (-6 + 7)x - 10
Step 5 = 10 + x - 10
Step 6 = x + 10 - 10
Step 7 = x + 0
Step 8 = x

Answer 2

I think it is associative.

Answer 3

Indicate which property is illustrated in Step 1.

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