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
