Question 938484
Which ordered pair makes the equation true? 2x=12-3y

A (1,-3) 
B (2,6)
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/3}}}
---
You can see from that that x has to be a multiple of 3 which eliminates A & B.
