Answer 1

x = -5

y = = 25 - 9 - 16

---------------------------------

x = -4

y = = 16 - 9 = 7

---------------------------------

x = -3

y = = 9 - 9 = 0

---------------------------------

x = 0

y = -9

--------------------------------

x = 2

y = - 9 = 4 - 9 = -5

-------------------------------

x = 3

y = 0

--------------------------------

x = 6
