and the 3y-4x has a bar over it.
Answer by hailu(13)   (Show Source):
You can put this solution on YOUR website! 5x-[(-3x+2y-5x)-(10x-3y-4x)]
=>if u have a negative solution, u change the negative sign into an addition, and change all the signs of the no.s that come after the negative sign:
5x-[(-3x+2y-5x)+(-10x+3y+4x)]
5x-[(-3x-10x)+(2y+3y)+(-5x+4x)]
5x-(-13x+5y-1x)
5x-(-14x+5y)
=>same step applies, you have to change the negative sign into a positive,and signs that come along:
5x+(14x-5y)
=19x-5y
dats yo answer,u'r welcome!
