Answer:

y = -3x-9

Step-by-step explanation:

To solve for y, we need to subtract 7 from each side

7-7 + y = -2-7 -3x

y = -3x-9

For x:

[tex]-2-3x=7+y[/tex]             add 2 to both sides

[tex]-3x=9+y[/tex]          divide both sides by (-3)

[tex]\boxed{x=-3-\dfrac{1}{3}y}[/tex]


For y:

[tex]7+y=-2-3x[/tex]      subtract 7 from both sides

[tex]\boxed{y=-9-3x}[/tex]
