Answer 1

3. Z=10 4. B=60

Explanation:

For number 3 we work backwards. So, 6 - (-4) would equal 10. To check this -4 + 10 = 6. For number 4, we also work backwards, so 12 x 5 = 60. To check this 60/5 = 12. So z = 10 B = 60.

Answer 2

Answer: 1.) 10

Explanation:

-4 + 4 = 0

0 + 6 = 6

6 + 4 = 10
