    Lets x and y are the value of two numbers.

    x + y = 16

    x - y = 2.4

    If x + y = 16 then x = 16 - y

    Substitute x = 16 - y into x - y = 2.4

    16 - y - y = 2.4

    16 - 2y = 2.4

    2y = 13.6

    y = 6.8

    x = 16 - y

    x = 16 - 6.8

    x = 9.2

    Answer:

    The value of two numbers are 9.2 and 6.8
