8(2w-2)=7(7w+2)
We move all terms to the left:
8(2w-2)-(7(7w+2))=0
We multiply parentheses
16w-(7(7w+2))-16=0
We calculate terms in parentheses: -(7(7w+2)), so:We get rid of parentheses
7(7w+2)
We multiply parentheses
49w+14
Back to the equation:

16w-49w-14-16=0
We add all the numbers together, and all the variables
-33w-30=0
We move all terms containing w to the left, all other terms to the right
-33w=30
w=30/-33
w=-10/11
