-4x + 1 = 21

• x = 120

• x = 5

• x = 30

• x = -5

After subtracting 5 from both sides of the equation (3x + 5 = 20), what will the equation look like?

• 3x = 25

• 3x = 20

• 3x = 3

• 3x = 15

• addition

• subtraction

• multiplication

• division

What is the first step to solve this equation:

11 - 3x = 44?

• Add 3 to both sides

• Subtract 11 from both sides

• Add 11 to both sides

• Divide by 3 on both sides
