Math Solve for both systems 4x + 4y = 12 and - 4x - y = - 30 Asked by AnneS2 on 26 Aug 11:24 Last updated by anonymous on 27 Aug 15:07

4x + 4y = 12 4x-4x + 4y = 12-4x 4y = 12-4x 4y/4 = 12-4x/4 y=3-x - 4x - y = - 30 - 4x - (3-x)= - 30 -4x+3+x=-30 3x+3=-30 3x+3-3=-30-3 3x=-33 3x/3=-33/3 x=-11 y=3-x y=3-(-11)=3+11=14
