Question

-4(2z+6)-12=4. HAAAAAAAAALP. please include explanation.

Answer 1

Z = -5

Explanation:

1) multiply bracket

-4 x 2z = - 8z

-4 x 6 = - 24

2) put back into equation

-8z - 24 - 12 =4

3) collect like terms

-8z - 36 =4

4) get z alone

-8z - 36=4

+36 +36

-8z = 40

5) find z

-8z =40

divide both sides by - 8

Z= - 5

Answer 2

z = -5

Explanation:

-4(2z+6)-12 = 4

=> -8z - 24 - 12 = 4

=> -8z = 4 + 12 + 24

=> -8z = 40

`= > z = (40)/( - 8)`

=> z = - 5 (Ans)
