Step-by-step explanation:

I don't know if you do this the same way I did, but..

The first step is to subtract 9 on both sides, like this.

13w + 9 = 178

       -9    -9

You'll end up with:

13w = 169

I don't know if you need the answer or not but I'll help you out.

For the second step, divide both sides by 13w.

13w = 169

/13w   /13w

 w = 13

Hope this helped!
