Answer:

z stands for 3.

Explanation:

First, subtract 12 from both sides.

-8z + 12 - 12 = -12 - 12

-8z = -24

Next, let's put brackets [] between both numbers. Any number inside of these becomes positive.

[-8z] = [-24]

8z = 24

Finally, let's divide doth sides by 8!

8z/8 = 24/8

z = 3

Answer:

z is a variable so it can be any number.

z=-3

if you do -8 times -3 that equals 24.

the answer is -3
