Solve for y:

5x - y = -16

• y = -21x

• y = (-16/5)x

• y = -5x - 16

• y = 5x + 16

Solve for y:

-3x - 2y = 18

• y cannot be isolated unless you know the value of x

Tags

CCSS.6.EE.C.9

• subtract m from both sides

• multiply both sides by x

• add c to both sides

• divide both sides by m

• x = -16

• x = -1

• x = -16/21

• x = -1/3
