Question

Solve the equation, 3x – 6 = 12, for x. Which of the following properties did you apply? Question 20 options: A) Distributive property, subtraction property of equality, and multiplication property of equality B) Distributive property, addition property of equality, and division property of equality C) Addition property of equality and division property of equality D) Addition property of equality and multiplication property of equality

Answer 1

C) Addition property of equality and division property of equality

Explanation:

To find the answer, let's first solve the equation for x...

3x-6=12

Add 6 to both sides (Addition property of equality)

3x=6

Divide both sides by 3 (Division property of equality)

x=2

We used both the addition property of equality and the division property of equality therefore the answer is C
