    Question Which side first?

    Hi,

    I am wondering a few basic algebra principals. So let's say I've got an equation that looks like this:

    3x + 4 = 4x - 5

    And I want to solve for x.

    Which side do I subtract from? Does it matter? The lowest integer or which side? Please explain. Thanks.

    It does not matter. You will get the same solution.

    If you get x on the right, you will have -x = ..., so you will need to multiply by -1 to get x = .... Still the same answer though.
