    The answer is C

    What you need to do is plug in 3x+2 (-3x) = 6 then solve for x.

    X=-2

    C is the only answer with x=-2

    y = - 3x

    3x + 2y = 6

    A) 3x + y = 0

    B) 3x + 2y = 6

    Multiply A) by - 1

    A) - 3x - y = 0 then add to B

    B) 3x + 2y = 6

    y = 6

    3x + 6 = 0

    3x = - 6

    x = - 2

    Answer is C
