Question

Indicate which property is illustrated in Step 8.

Step 1 11 - 5x - 11 + 6x = (11 - 5x) + (-11 + 6x)
Step 2 = (11 - 5x) + (6x - 11)
Step 3 = 11 + (-5x + 6x) - 11
Step 4 = 11 + (-5 + 6)x - 11
Step 5 = 11 + x - 11
Step 6 = x + 11 - 11
Step 7 = x + 0
Step 8 = x

commutative
identity
distributive
associative

Answer 1

there is additive identity which is when you add 0
it goes away because number + 0 = number
and there is multiplicative identity which is when you multiply by 1
it goes away because number * 1 = number

Answer 2

so it would make it identity

Answer 3

yes :)
