The coordinates -7, -3, 3, and 7 are all candidates for the site of Carl's home.
This is further explained below.
Generally, According to the information provided in the question, Ann's home occupies position 0 on a number line, and Beth's residence is situated 5 blocks away from Ann's. Therefore, places 5 and -5 on the number line are both candidates for where Beth may be.
Carl lives two blocks away from Beth, which means that he either stays two blocks closer to Ann than he does to Beth or two blocks farther away from Ann than he does to Beth.
In conclusion, On the number line, moving closer to Ann by two blocks equals the number 3, while moving further away from Ann by two blocks equals the number 7. On the positive side of the number line, this means that Carl may be located anywhere between 3 and 7.
On the other side of the number line, Carl may be located anywhere between -3 and -7. These are the conceivable outcomes.
