    okay -x-x? that is -2x because when we have -vs- we add. X has conf of one when no value is being denfined 3x+10 because again you are adding 1 which is what the x has a value of.

    unless the -2 has and x like this -2x you can not put together. since our -2-x-x the only thing you can do here is -2 -2x terms don't match.
