Question

Indicate which property is illustrated in Step 2.

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

distributive
associative
commutative
identity

Answer 1

Step 2: Commuttative Propert for Additon states a + b + b+ a, so -10 + 6x = 6x - 10.
