PLug in the values and see.
I'll do one, you do the rest.
2x=12-3y
2%281%29=12-3%28-3%29
2=12%2B9
2=21
False.
Do the same for the other 4.

Which ordered pair makes the equation true? 2x=12-3y

C (-9,-2)
D (3,2)
---------------
Sub for x & y to find out.
It might be easier if you solve for y:
---
2x=12-3y
3y = 12 - 2x
y+=+4+-+2x%2F3
---
You can see from that that x has to be a multiple of 3 which eliminates A & B.
