Answer

$$(1,2), \quad (0,5/3), \quad (-4,1/3 ).$$

Work Step by Step

Substitute the value of $x$ and solve for $ y $ to get the ordered pair $ (x,y)$ as follows: $$ 3y -(1) = 5 \Longrightarrow 3y=1+5 \Longrightarrow y =2 ,$$ $$ 3y -(0) = 5 \Longrightarrow 3y=5 \Longrightarrow y =5/3 ,$$ $$ 3y -(-4) = 5 \Longrightarrow 3y=-4+5 \Longrightarrow y =1/3 ,$$ Hence, we have the pairs $$(1,2), \quad (0,5/3), \quad (-4,1/3 ).$$
