Find the quotients in each group below. is division commutative?

- 2 ÷ 3 = - 0.667 and 3 ÷ (- 2) = - 1.5.

- 12 ÷ (- 4) = 3 and - 4 ÷ (- 12) = 0.333.

16 ÷ 8 = 2 and 8 ÷ 16 = 0.5.

Division is not commutative.

Step-by-step explanation:

We have to find the quotients in each group as given in the attachment.

- 2 ÷ 3 = - 0.667 and 3 ÷ (- 2) = - 1.5. So, - 2 ÷ 3 ≠ 3 ÷ (- 2)

- 12 ÷ (- 4) = 3 and - 4 ÷ (- 12) = 0.333. So, - 12 ÷ (- 4) ≠ - 4 ÷ (- 12)

Now, 16 ÷ 8 = 2 and 8 ÷ 16 = 0.5. So, 16 ÷ 8 ≠ 8 ÷ 16

From the above examples, we can say division is not commutative. (Answer)

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
