Answer
$$(3, -2), \quad (0,-4), \quad (-3,-6 )$$
Work Step by Step
Substitute the value of $x$ and solve for $ y $ to get the ordered pair $ (x,y)$ as follows:
$$
2(3)- 3y = 12 \Longrightarrow - 3 y=6 \Longrightarrow y =-2
,$$
$$
2(0)- 3y = 12 \Longrightarrow - 3 y=12 \Longrightarrow y =-4
,$$
$$
2(-3)- 3y = 12 \Longrightarrow - 3 y=18 \Longrightarrow y =-6
,$$
Hence, we have the pairs
$$(3, -2), \quad (0,-4), \quad (-3,-6 )$$
