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