    Answer:

    x=-3 and y=-2

    Step-by-step explanation:

    let the numbers be x and y

    x+y=-5

    x-y=-1

    therefore x=-5-y

    -5-y-y=-1

    -2y=-1+5

    -2y=4

    y=-2

    ×=-5-(-2)

    x=-5+2

    x=-3

    Answer: -2 and -3

    Step-by-step explanation:

    • Number #1 = x
    • Number #2 = y

    x + y = -5

    x – y = -1 -> x = y – 1

    (y – 1) + y = -5

    y – 1 + y = -5

    2y = 1 – 5

    2y = -4

    y = -2

    x = y – 1 = -2 – 1 = -3
