okay, so let’s work this out.
We have to use the distributive property to get rid of the parenthesis.
Multiply the 2 by each thing inside of the parenthesis
2 ( w + 3 ) - 4w
2w + 6 - 4w
Add Like Terms (w)
-2w + 6
Now I am not sure whether you are just simplifying the equation or solving for w, so make sure to be more clear about that next time.
I simplified the problem, so you should be able to take it from here.
