    Answer:x=-1 y=1

    Step-by-step explanation:

    -3y+10x=-5

    3y-6x=9

    Add both equations together

    -3y+3y+10x-6x=-5+9

    0+4x=-4

    4x=-4

    Divide both sides by 4

    4x/4=-4/4

    x=-1

    Substitute x=-1 in 3y-6x=9

    3y-6(-1)=9

    3y+6=9

    3y=9-6

    3y=3

    Divide both sides by 3

    3y/3=3/3

    y=1
