-35 x 4 = -140

-140 is your answer

hope this helps

Yaneev thinks of a number y. He subtracts three from the number, then doubles it. Then he subtracts three again, and doubles the
Sergio039 [100]

Answer: y=6

Step-by-step explanation:

The given number is y.

According to the question,

Step 1 . subtracts three from the number (y-3), then doubles it

i.e. Final number = 2(y-3)

Step 2 .  subtracts three again i.e. (2(y-3)-3), and doubles the number again

i.e. Final result  = 2(2(y-3)-3)

If the result is his original number y, then

2(2(y-3)-3) =y

⇒ 2(2y-6-3)=y   [ using distributive property]

⇒ 2(2y-9)=y

⇒ 2(2y)-2(9)=y [ using distributive property]

⇒ 4y -18=y

⇒ 4y -y= 18 

⇒ 3y= 18

⇒ y= 6    [Divide both sides by 3]

Hence,  y=6
