Question

Please help me with 12 and the question below it, plz thank youuu!!!

Answer 1

SECOND PART:
7+19=26
7-19=-12
Nails favorite number could be 26 or -12 because Nails favorite number could be 19 units before Sasha's or after.

Answer 2

13 units from 20 could either be 33 or 7; 15 units from -8 could either be 7 or 23.Since 7 satisfy both of the above requirements, Sarah's favorite number is 7. (You could show your work using a number line)

The two possibilities of Neil's favorite number are 26 and -12.
