    Answer:

    11, 76

    Step-by-step explanation:

    Let the two numbers be x and y.

    According to the given conditions:

    x + y = 87…..(1)

    x – y = 65….(2)

    Adding equations (1) & (2)

    x + y = 87

    x – y = 65

    __________

    2x = 152

    x = 152/2

    x = 76

    Plug x = 76 in equation (1)

    76 + y = 87

    y = 87 – 76

    y = 11

    Thus the two numbers are 11 and 76.

    Step-by-step explanation:

    Let the two numbers be x and y

    By the question

    x + y = 87 ..... equation (I)

    x y = 65 ...... equation (II)

    Now adding both equations we get

    2x = 152

    x = 152 / 2

    Therefore x = 76

    Putting x = 76 in equation i

    76 + y = 87

    y = 87 76

    Therefore y = 11

    The two numbers are 76 and 11.

    Hope it helps :)
