How do you get a variable term from one side of an equation onto the other side?

Can I get an example please?

Subtract it from both sides.
It is the same thing as changing the sign and moving it to the other side.

Example: 3x+7=9x-15
So your going to subtract 3x from both sides. You should end up with 7=6x-15. So now your giong to add 15 to both sides. You should get 22=6x.

Hope that helps!! :)
