Question

Solve the equation, 3x – 6 = 12, for x. Which of the following properties did you apply? Question 1 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 multiplication property of equality D) Addition property of equality and division property of equality

Answer 1

Answer:

D) Addition property of equality and division property of equality

Step-by-step explanation:

Step(i):-

Given equation 3 x -6 =12

Apply addition property of equality

Adding '6' on both sides , we get

                       3 x - 6 + 6 = 12 +6

                       3 x  = 18

Step(ii):-

Apply Division property of equality

Dividing '3' on both sides , we get

                       $\frac{3 x}{3} = \frac{18}{3}$

on simplification , we get

                      x = 6

Conclusion:-

The solution of the given equation  is x =6
