    a+b = 22

    a-b = 16

    2a = 38

    a = 19 ; b = 22-19 = 3

    The numbers are 3 and 19.

    x + y = 22

    x - y = 16

    Add the equations together (note the "-y")

    2x = 38

    x = 19

    Substitute into x + y = 22

    19 + y = 22

    y = 3

    ANS 19 and 3

    x + y = 22

    x - y = 16

    _________ add

    2x = 38

    x = 19

    so y = 22 - 19

    y = 3

    The sum of two numbers is 22 and their difference is 16.

    x + y = 22, x - y = 16

    The two numbers are 19 and 3.

    (22+16)/2 = 19 and (22-16)/2 = 3

    Let a be the bigger number.

    Let b be the smaller number.

    Write two equations:

    a + b = 22

    a - b = 16

    Add them together:

    2a = 38

    a = 38/2

    a = 19

    Then solve for b:

    19 + b = 22

    b = 3

    Answer:

    3 and 19
