Okay, so say I have an equation that looks like this:(adsbygoogle = window.adsbygoogle || []).push({});

9y - 4x + 5 = 0

and I wan to move every thing but the y over to the right hand side.

When it gets to the last step and looks like this:

9y = 4x - 5

When I move 9 over to the other side, does it's sign change? I know the other terms will be divided by it, but I don't remember if it is supposed to be negative... my text has examples that aren't quite clear.

Thanks!
