Let the required original number be " x "

According to the given problem,

`7(x + 3) = 28 \\ (x + 3) = (28)/(7) \\ (x + 3) = 4 \\ x =(4 - 3) \\ \boxed{x = 1}`

• Hence, the original number is 1.
• 1 is the right answer.

`\large \boxed{ \mathfrak{Explanation}}`

Let the number be represented as " x "

from the given statement we can infer that :

• 
  `7(x + 3) = 28`

So, let's find the value of " x " from the given equation ~

• 
  `x + 3 = 28 / 7`

• 
  `x + 3 = 4`

• 
  `x = 4 - 3`

• 
  `x = 1`
