2x + y = 18 |y|
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?
Answer/Solution
19
Steps/Work
Hi - The questions says |y| <=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.E
