    Answer:

    ( -19,55)

    Step-by-step explanation:

    y=-3x – 2

    5x + 2y = 15

    + First, we replace y = -3x -2 into 5x + 2y =15

    and we have 5x + 2( -3x -2) =15

    or 5x – 6x – 4 =15

    or -x -4 =15

    and -x -4 +4 = 15 +4

    finally -x = 19, or x= -19.

    Replace x = -19 into y = -3x -2 = -3*(-19) -2 = 57 -2 =55

    The solution is (x, y) or ( -19, 55), we choose b)

    Have a good day.
