Not sure how to work this

Answer:

First ordered pair: (-4,-3)

Second ordered pair: (8,3)

Step-by-step explanation:

To find the missing coordinate, all we have to do is to plug it into the corresponding variable and solve.

First Ordered Pair

x-2(-3)=2 [multiply -2 and -3]

x+6=2 [subtract 6 on both sides]

x=-4

(-4,-3)

Second Ordered Pair

8-2y=2 [subtract 8 on both sides]

-2y=-6 [divide both sides by -2]

y=3

(8,3)
