Step-by-step explanation:
Let "a" represent Alondra's number. Then the math she performs on it is ...

This absolute value expression can be "unfolded" to two of them ...
-2 < 2a -6 < 2
Dividing by 2 gives ...
-1 < a -3 < 1
Adding 3, we get ...
2 < a < 4
The only whole number in this range is ...
a = 3
