Let’s assign variable to use in every person in the
given situation.
let x be the value of George’s number of words on his page
let y be the value of Bills number of words in his page
and let z be the value of words on Charlie’s page
=> X = 2(Y)
=> Y = Z – 50
They type 60 words per second.
=> 2Y – Z= 210
Now, let’s start solving:
2Y + 0 – X = 0
Y – Z + 0 = 50
2Y – Z + 0 = 210
Thus the number of Bill’s word number on his page is 260.
