Answer
$$(1,-2), \quad (0,-12/7), \quad (-8,4/7).$$
Work Step by Step
Substitute the value of $x$ and solve for $ y $ to get the ordered pair $ (x,y)$ as follows:
$$
2(1)+ 7y = -12 \Longrightarrow 7y=-12-2 \Longrightarrow y =-2
,$$
$$
2(0)+ 7y = -12 \Longrightarrow 7y=-12 \Longrightarrow y =-12/7
,$$
$$
2(-8)+ 7y = -12 \Longrightarrow 7y=-12+16 \Longrightarrow y =4/7
,$$
Hence, we have the pairs
$$(1,-2), \quad (0,-12/7), \quad (-8,4/7).$$
