Answer:

The number is 12

Step-by-step explanation:

Let the number be x

Triples it,

3x

Add three, and gets 39 as the result.

3x + 3 = 39

3x + 3 - 3 = 39 - 3

3x = 36

3x/3 = 36/3

x = 12

Here,

We assumed Carla's number would be x,

So,

12 × 3 + 3 = 39

36 + 3 = 39

Thus, Carla's number is 12
