Answer:
(0,3) and (7,0) are solutions.
Step-by-step explanation:
In a pair of coordinates, they are always listed as (x,y). Since this is the case, you plug in each coordinate to their respective places.
For (0,3)
3(0) + 7(3) = 21
0 + 21 = 21
For (7,0)
3(7) + 7(0) = 21
21 + 0 = 21
To double check that (1,2) isn't a solution:
3(1) + 7(2) = 21
3 + 14 = 21
17 = 21 X
This doesn't work.

Step-by-step explanation:
Do you have a picture or is that it?
1/2 * 2/2 = 2/4 which is not 2/7
2/1 * 7/7 = 14/7 which is not 7/14
1/2 * 7/7 = 7/14 which is 7/14 yes
2/1 * 7/7 = 14/7 which is not 14/21 no
