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!

She has 11 friends,
20 of the balls=5 friends and the rest =6 friends. I may be wrong so check this for yourself to be sure. :)
So with 1 cup of sugar u could have 18 servings. divide that by 2 equals 9 which is how many servings you need. divide 1 by 2 and get 1/2. she would use 1/2 cups of sugar.
