{(-5, -3)}
{(1, 1)}
{(5, 3)}

Answer 1

There's the quick and easy way to do this, it can only be done when you are given choices...or we can pretend that there aren't any choices :D

Answer 2

Answer 3

i dont understand it at all

Answer 4

Well, let's try the second choice.
(1,1)
replace the x's with 1's and the y's with 1's.
1+2(1) = 11
Which isn't true... so (1,1) IS NOT THE ANSWER
