Two Step Equations

What is the first step in this equation?

3x + 5 = 20

• Add 5 and 20

• Subtract 5 from both sides of the equation

• Add 3 and 5

• Multiply 3 by 5

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

• 3x = 25

• 3x = 20

• 3x = 3

• 3x = 15

What is the next step in the equation?

3x = 15

• Divide both sides by 3

• Add 3 and 15

• Subtract 3 and 15

• Multiply 3 and 15

What is the final answer?

• 45

• 18

• 5

• 12
