Question

Solve for 7 + y = -2 -3x

Answer 1

For x:

$-2-3x=7+y$             add 2 to both sides

$-3x=9+y$          divide both sides by (-3)

$\boxed{x=-3-\dfrac{1}{3}y}$

For y:

$7+y=-2-3x$      subtract 7 from both sides

$\boxed{y=-9-3x}$

Answer 2

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
