Answer:
y = -1
x = 1
Step-by-step explanation:
as I have done the equation in the picture, I decided to re-write the second equation so that it's easier for me to use.
You're thinking b=1 will always give an integer, certainly true.
Then you think b=-1 will also always give an integer, so
Answer: ±1
Then you remember that a/b may not be a reduced fraction, so other bs beside the unit make give integers. The condition for an integer is
b | a
read 'b divides a' meaning a is a multiple of b.
Then you realize that a and b might not even b integers themselves.
Let's say the above answer is correct with the additional criteria that a and b are integers with no common factors.
Answer:
I think it should be 11/3
