W=12 would be the correct answer. I got this because if you divided 12 by 2, (12/2) you would get 6!
All you need to do is solve it

or

When solved your answer is
0.25 or 1/4
------------------------
What I did to solve it was....
1. Divide top fraction by bottom fraction to get decimal
1 ÷ 2 = 0.5
2. Then multiply 0.5 by its self (the same as putting it to the ^2)
0.5 x 0.5 = 0.25
Answer:
-7 =x
Step-by-step explanation:
−30=5(x+1)
Divide each side by 5
−30/5=5/5 (x+1)
-6 = x+1
Subtract 1 from each side
-6-1 = x+1-1
-7 =x
