transposing a formula

[sstrasner]

Hi. Here is a math problem I am having trouble with and my math book isn't helping much.

2Z * 3Z/ 4.5= 2Z

Here is how I'm trying to do it.

6Z/4.5= 2Z

6Z= 4.5 * 2Z

6Z= 10Z

I don't know what else?

4.5 * 2 is 9...so,
6Z = 9Z
6Z= 10Z

I removed my original response, since I overlooked the obvious error that 2Z*3Z = 6Z[sup:3huyi62p]2[/sup:3huyi62p]. Follow Denis's advice!

2Z * 3Z/ 4.5= 2Z
Here is how I'm trying to do it.
6Z/4.5= 2Z

2Z * 3Z = 6Z^2, not 6Z
SO:
6Z^2 = 9Z ; finish it
