Question 70106: The difference when 7 less than a number is subtracted from twice the number is 12. What is the number? Answer by psbhowmick(878) (Show Source):
You can put this solution on YOUR website! Let the number = x.
Twice the number = 2x.
7 subtracted from twice the number (which is x)= (x - 7).
When this number is subtracted from twice the original number the difference = 2x - (x - 7) = x + 7
This value is given = 12
So, x + 7 = 12
or x = 12 - 7 = 5
So the reqd. number is 5.
