Select the property of equality used to arrive at the conclusion
If x= 3, then x2 = 3x

You used the fact that you can multiply both sides of an equality by the same, non-zero constant.

So, if you start with the trivial equality

you can multiply both sides by 3:

But if , becomes , which is . So, we have

which leads to

if you recall that

answer: .64
