Answer
$$(3,5/2), \quad (0,4), \quad (-4,6 )$$
Work Step by Step
Substitute the value of $x$ and solve for $ y $ to get the ordered pair $ (x,y)$ as follows:
$$
3+ 2y = 8 \Longrightarrow 2 y=5 \Longrightarrow y=\frac{5}{2}
,$$
$$
0+ 2y = 8 \Longrightarrow 2 y=8 \Longrightarrow y=4
,$$
$$
-4+ 2y = 8 \Longrightarrow 2 y=12 \Longrightarrow y=6
,$$
Hence, we have the pairs
$$(3,5/2), \quad (0,4), \quad (-4,6 )$$
