Answer:

Addition Property of Equality

Step-by-step explanation:

So we had:

[tex]3x-2=7[/tex]

And then we got:

[tex]3x=9[/tex]

We did this by adding 2 to both sides of the equation. When we added 2, the left side cancelled and the right side equated to 9:

[tex](3x-2)+2=(7)+2\\3x=9[/tex]

Since we added 2 to both sides, this is an example of the addition property of equality.
