Which TWO systems of linear equations are solved correctly?
A) If x + y = 3 and 2x + y = 12, then x = 9 and y = β6.
B) If 5x + y = 10 and x + 2y = 8, then x = 10 3 and y = 4 3 .
C) If x + y = 7 and 6x + y = 2, then x = 3 2 and y = 11 2 .
D) If 2x + 2y = 4 and x β 4y = 12, then x = 4 and y = β2.
E) If 2x β 4y = 4 and x β 6y = 10, then x = 2 and y = 2.
