It's elimination

-x+6y=3

-4x-2y=-14

(3,1)

Step-by-step explanation:

Multiplying the second equation by 3, we get

-12x-6y=-42.

Now, adding this to the first equation, we get

-13x=-39

Therefore, x=3

plugging in x=3 to the first equation, we get that

-3+6y=3

adding 3 to both sides,

6y=6

therefore, y=1
