Question

Indicate which property is illustrated in Step 3.

Step 1 11 + 11x - 11 - 2x + 3 = 11 + (11x - 11) - 2x + 3
Step 2 = 11 + (-11 + 11x) - 2x + 3
Step 3 = [11 + (-11)] + (11x - 2x) + 3
Step 4 = 0 + (11x - 2x) + 3
Step 5 = (11x - 2x) + 3
Step 6 = (11 - 2)x + 3
Step 7 = 9x + 3

Answer 1

this one is a bit different

Answer 2

going from step 2 to step 3 is still just grouping changes

Answer 3

associative

Answer 4
