@Directrix

directrix · Answer

The task is to justify why it is that this is true:

If              3 = 2x
then      3/2 =   x

So, look at that. What operation went on to change 2x to x and also change 3 to 3/2 at the same time?

anonymous · Answer

Division?

directrix · Answer

Yes. Division Property of Equality.

Dividing by 2 is the same as multiplying by 1/2 so it could also be Multiplication Property of Equality.

What sort of options do you have?
