-3 = w

Step-by-step explanation:

First, we need to isolate -6w.

In order to do that, we subtract 12 from both sides.

30 - 12 = 18, and 12 - 12 is 0. So now we're left with 18 = -6w.

Next we need to isolate w. We have to divide -6 from both sides to do so.

18 divided by -6 is -3, and  -6 divided by -6 is 0.

Therefore, -3 = w.

Hope this helps!
