Sarah says that both of these equations are equivalent. Which statement explains why this is true? 

Equation A:    $$2\left(x+6\right)=-12$$  

Equation B:  $$x+6=-6$$  

• subtracting 2 from both sides of Equation A gives  $$x+6=-6$$  

• applying the distributive property to Equation A gives  $$x+6=-6$$  

• dividing both sides of Equation A by 2 gives  $$x+6=-6$$  

• adding 2 to both sides of Equation A gives you  $$x+6=-6$$
