Question

If 3 is added to a number and the sum is tripledtripled​, the result is 27 more than the number. find the number.

Answer 1

To solve this problem, let us say that the number is called x and let us do this step by step.

 

1st step: 3 is added to the number, therefore:

x + 3

 

2nd step: the sum is tripled, therefore:

3 (x + 3)

 

3rd step: the result in the 2nd step is equal to 27 more than the original number, therefore:

3 (x + 3) = x + 27

 

4th step: find for the value of x using the equation

3 x + 9 = x + 27

3 x – x = 27 – 9

2 x = 18

x = 9

 

Answer:

The number is 9
