-4(w-9)=3w+8

We move all terms to the left:

-4(w-9)-(3w+8)=0

We multiply parentheses

-4w-(3w+8)+36=0

We get rid of parentheses

-4w-3w-8+36=0

We add all the numbers together, and all the variables

-7w+28=0

We move all terms containing w to the left, all other terms to the right

-7w=-28

w=-28/-7

w=+4
