    3x+y=-11

    3x+y+-3x=-11+-3x (Add - 3x to both sides)

    y=-3x-11

    2x+2y=-10

    2x+2 (-3x-11) = -10

    -4x-22=-10 (Simplify both sides of the equation)

    -4x-22+22=-10+22 (Add 22 to both sides)

    -4x=12

    -4x

    -4

    =

    12

    -4

    (Divide both sides by - 4)

    x=-3

    y=-3x-11

    y = (-3) (-3) - 11

    y=-2 (Simplify both sides of the equation)

    Answer:

    x=-3 and y=-2

    D. (-3,-2)
