Answer:
1. 10
2. if x was positive
3. if x was negative
Step-by-step explanation:
1. he starts on -2. so -2 + 12 is 10, so he would be on the space number 10.
2. if he moved to the right, it would mean you added something to 3. so, if x was positive, then it would move to the right.
3. if he moved to the left, it would mean that you subtracted something from 3. so, if x was negative, then it would move to the left.
