Math Solve for both systems x + 2y = 1 and - 4x + 2y = 16 Asked by AnneS2 on 24 Aug 06:24 Last updated by anonymous on 25 Aug 15:55

x + 2y = 1 x + 2y-2y = 1-2y x= 1-2y - 4x + 2y = 16 - 4(1-2y) + 2y = 16 - 4(1) (-4)(-2y) + 2y = 16 -4+8y+ 2y = 16 -4+10y = 16 -4+10y +4= 16+4 10y=20 10y/10=20/10 y=2 x= 1-2y x= 1-2(2) x= 1-4=-3
