2(w-2)-4w=2(w-9)
We move all terms to the left:
2(w-2)-4w-(2(w-9))=0
We add all the numbers together, and all the variables
-4w+2(w-2)-(2(w-9))=0
We multiply parentheses
-4w+2w-(2(w-9))-4=0
We calculate terms in parentheses: -(2(w-9)), so:We add all the numbers together, and all the variables
2(w-9)
We multiply parentheses
2w-18
Back to the equation:
-(2w-18)
-2w-(2w-18)-4=0
We get rid of parentheses
-2w-2w+18-4=0
We add all the numbers together, and all the variables
-4w+14=0
We move all terms containing w to the left, all other terms to the right
-4w=-14
w=-14/-4
w=3+1/2
