    Ur 2 numbers are represented by x and y

    x + y = 82 ... their sum is 82

    x - y = 24 ... their difference is 24

    too bad u have to use substitution, elimination would have been easier

    x + y = 82 ... x = 82 - y ... so sub in 82 - y in for x in the other equation

    x - y = 24

    82 - y - y = 24

    82 - 2y = 24

    -2y = 24 - 82

    -2y = - 58

    y = - 58/-2

    y = 29

    x + y = 82

    x + 29 = 82

    x = 82 - 29

    x = 53

    so ur 2 numbers are 53 and 29
