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

Addition Property of Equality

Division Property of Equality

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 :)
