12x = 144

• x = 12
• x = 4
• x = 2
• x = 132

-4x + 1 = 21

• x=120
• x=5

What is the first step to solve this equation:

- 3x -11 = 44

• Add 3 to both sides

• Subtract 11 from both sides

• Add 11 to both sides

• Divide 3 on both sides.

Solve for x:

2x - 3 = 1

• x = 3

• x = 2

• x = 1

• x = -2

Solve for b:
 3(b - 4) = -3

• b = 3
• b = -3
• b = 5
• b = -5

Solve for x:

2x -1(3+4x) = 11

• x = -4

• x = 7/3

• x = -7

• x = -17/8

Solve for k:

38 + 7k = 8(k + 4)

• k = 6

• k = 8

• k = -6

• k = 1
