Which THREE systems of linear equations are solved correctly? es =) A) If 2x + 4y = 6 and x + 8y = 12. then x = 0 and B) If x + 3y = 5 and x + y = 1, then x= -1 and y = 2. 다. If x - 3y = 12 and 2x + 2y = 4. then x = and y D) If x - 6y = 6 and x – 4y = 4, then x = 0 and y = -1, E) lf x - 3y = 3 and x - 2y = -4, then x = 18 and y = 7​
