Answer 1

Is this it?

\(2 - \dfrac{z}{3} = 12\)

Answer 2

yes

Answer 3

Or is it this one?

\(\dfrac{2 - z}{3} = 12\)

Answer 4

the first one

Answer 5

Okay..so first we subtract 2 to both sides.. what's 12 - 2?

Answer 9

10

Answer 10

Yes, that gives us:

\(- \dfrac{z}{3} = 10\)

Now we multiply 3 * 10.

Answer 11

=30

Answer 12

\(-z = 30\)

Yes, now we divide -1 to both sides, what's 30 / -1?

Answer 13

-30

Answer 14

Yep, so that's your answer.

Answer 15

wait isn't that one of the answer choices?

Answer 16

Yes..that's C..-30.
