8x + 4y= 16

• y = -8x + 16
• y = 2x -4
• y = -2x + 4
• y = -8x + 12

Solve for y:

y + 2 = 3x

• y = 2x + 3

• y= 3x +2

• y= 3x -2

• y= 6x

Solve for y

3x + y = 12

• y = -3x +12
• x = y + 4
• x = y + 12
• y = 3x -12

Solve for y:
2x + 2y = 6

• y = - x + 3
• y = x + 3
• y = 2x +6
• y = - 2x + 6

Rewrite this formula and solve for the variable y. 6x + 3y = 48

• y = 2x - 16

• y = -2x + 16

• y = -2x - 16

• y = 2x + 16

Rewrite this formula and solve for the variable y. 7y = −28x - 56

• y = −4x + 8

• y = 4x + 8

• y = −4x - 8

• y = 4x - 8

Rewrite this formula and solve for the variable y. 9x + y = 27

• y = 9x - 27

• y = 3 / x

• y = 3x

• y = −9x + 27

Solve for y

x = 3y - 24

• y = (x + 24)/3

• y = x/3 + 24

• y = 3x + 24

• y = 3(x + 24)

solve for y

y - x = 5

• y = 5 + x

• y = -5 - x

• y = -5 + x

• y = 5 - x
