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
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]
