    (-19; 55)

    Step-by-step explanation:

    y=-3x-2

    5x+2y=15

    (y+3x=-2) (-2)

    5x+2y=15

    -2y-6x=4

    5x+2y=15

    eliminate - 2y and 2y

    -x=19

    x=-19

    sub. x=-19 in eq. 2

    5 (-19) + 2y=15

    -95+2y=15

    2y=15+95

    2y=110

    y=110/2=55

    so (-19; 55) is the only solution for this system

    (hope that is the way you want the answer)
