Solve for y:
5x + y = -10

• y = 5x + 10

• y = -5x - 10

• y = 2

• y = -5

Solve for y:
2x + 2y = 6

• y = - x + 3

• y = x + 3

• y = 2x +6

• y = - 2x + 6

Solve for y:
y + 2 = 3x

• y = 2x + 3

• y= 3x +2

• y= 3x -2

• y= 6x

Solve for y:
3y -9 = 18x

• y=6x-3

• y=2x-3

• y=-6x+3

• y=6x+3

Solve for y: 
x + y = 4

• y = x + 4

• y = -x + 4

• x = -y + 4

• x= y - 4
