As shown in the attachment,
Step-by-step explanation:
Answer:
x=-1, y=5. (-1, 5). The first number is -1 and the second number is 5.
Step-by-step explanation:
6x+2y=4
2x+4y=18
---------------
-2(6x+2y)=-2(4)
2x+4y=18
-------------------------
-12x-4y=-8
2x+4y=18
----------------
-10x=10
x=10/-10
x=-1
6(-1)+2y=4
-6+2y=4
2y=4-(-6)
2y=4+6
2y=10
y=10/2
y=5
