Given :

A number is doubled and 9 is added. If the resultant is tripled it becomes 75.

To find :

The original number.

Solution :

Let the number is x

It is doubled = 2x

Then added 9 = 2x+9

Resultant is tripled. = 3(2x+9)

According to the given question :

=> 3(2x+9) = 75

=> 6x + 27 = 75

=> 6x = 75 - 27

=> 6x = 48

=> x = 48/6 = 8.

=> x = 8

Hence, the original number is 8.
