Question

Indicate which property is illustrated in Step 2.

Step 1 11 + 12x - 11 - 6x + 5 = 11 + (12x - 11) - 6x + 5
Step 2 = 11 + (-11 + 12x) - 6x + 5
Step 3 = [11 + (-11)] + (12x - 6x) + 5
Step 4 = 0 + (12x - 6x) + 5
Step 5 = (12x - 6x) + 5
Step 6 = (12 - 6)x + 5
Step 7 = 6x + 5

additive identity

distributive
additive inverse

Answer 1

It should be commutative
commutative law is true if changing the order of the operands does not change the result
