Question

Help me show work pls thank you show much :)

Answer 1

9) y=-1
-1+6=5 (you just subtract)
10) y=-77
17+-77=-60 (if you subtract; 77-17=60)

Answer 2

-1 is the first answer because if u subtract one from 6, it will equal 5
-77 is the second answer because adding positive 17 to that number will deduct the number to 60.
