the numbers inside the () are first number is x second number is y so it is (x,y)

so for y<x the second number needs to be smaller than the first number

 so right away (3,3) is not the answer

 and then y also has to be greater then 2x-3

 so replace x with the fist numbers and see what you get.

(2x2)-3 = 4-3 = -1 since -1 is not greater than -1 the second answer (2,-1) is not right

 3rd one (-1,-2) 2(-1)-3 = -2-3=-5

so -2 is greater than -5 and -2 is less than -1 so the 3rd one is the answer
