2x + y = 18
|y| <= 18
For how many ordered pairs (x , y) that are solutions of the system above are x and y both integers? Pick:	A) 11	B) 13	C) 15	D) 17	E) 19
Hi - The questions says |y| &lt;=18 so the values of y will range from 0 to 18.So the values of y will be 0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18. So 19 (E) is the answer. remember sign doesn't matter for y as y will always be positive.19
