Answer 1

Hi there! :)

Answer:

x=-6

*The answer must have a negative sign.*

Explanation:

First, you divide by -2 from both sides of an equation.

`(-2x)/(-2)=(12)/(-2)`

Then, you divide by the numbers from left too right.

`12/2=6`

It change positive to negative sign.

Final answer is x=-6

I hope this helps you!

Have a nice day! :)
