    Ok in order to isolate x in the first equation. What do you think you first step should be?

    It could be B but it also could be D depending if they want your to get rid of the - sign For instane -x = 2y - 4 and you could use this for a subsitution but if you get ride of the -, which they probably want you to do the answer is D
