Answer:
 7 (x - 1) = 14
gives: x = 3
Explanation:
Let the number be x
According to Given conditions:
- Difference of some number and 1 =  x - 1
 - Seven times the difference of some number and 1 = 7 (x - 1)
 - Quotient of 168 and 12 = 168/12 = 14
 
According to given scenario:
 7 (x - 1) = 14
Dividing both sides by 7
(x - 1) =2
Adding 1 on both sides:
x -1 +1 = 2 + 1
x = 3
