Y=3x-5 y-3x=-5 Times 2 from both side y(2)-3x(2)=-5(2) 2y-6x=-10 Times negative from both side (-)2y-6x(-)=(-)-10 -2y+6x=10 or 6x-2y=10
6x=2y+10 6x-2y=10 Furthermore, we see that both equation have the same 6x-2y=10 which means that both of them have infinity solutions, not a solution. Hope it help!
