Question

Zoe is solving the equation 3x – 4 = –10 for x. Which two properties of equality could Zoe use to finish solving for x?

Answer 1

Answer:

Addition Property of Equality

Division Property of Equality

Step-by-step explanation:

So we have the equation:

$3x-4=-10$

Addition Property of Equality

Add 4 to both sides:

$(3x-4)+4=(-10)+4\\3x=-6$

Division Property of Equality

Divide both sides by 3:

$(3x)/3=(-6)/3\\x=-2$

And that's our answer :)
