Solving Equations for a Variable

Solve for y:
y + 2 = 3x

• y = 2x + 3

• y= 3x +2

• y= 3x -2

• y= 6x

Solve for x:
8x - 10 = -34

• 4

• 3

• -3

• -24

Solve for w:
-6w + 1 = -11

• 2

• 1.2

• 12

• -2

Translate: 
Four times a number plus six IS 30.

• 4 + 6 = 30

• 4x + 6 = 30

• x + 4 times 6 = 30

• 30 = 4x

Solve:
-4x = 24

• 20

• -20

• 6

• -6

Solve:
3x + 7 = -8

• 5

• -5

• -12

• -18

Solve:
7x - 3x - 8 = 24

• 8

• -8

• 3.2
