A.
(0, 4)

B.
(6, 2)

C.
(3, 3)

D.
(0, −1)

Answers

Answer 1

Answer: -1*/x+3y=12
-4x+3y=-3

-x-3y= -12
-4x+3y= -3
+-------------------
-5x= -15
x=3

x+3y=12

3+3y=12

3y=9 y=3

(x,y)=(3,3)

Answer 2

Answer: $x+3y=12\n-4x+3y=-3\n\nx+3y=12\n4x-3y=3\n------\n5x=15\nx=3\n\n3+3y=12\n3y=9\ny=3\n\n(3,3)$
