    Answer:

    58 and 29

    Step-by-step explanation:

    Set up your equations:

    1) x + y = 87

    2) x – y = 29

    Use one of the equations to focus on when moving the numbers around such as for this one I used equation one:

    3) y = -x + 87

    x = (-x + 87) + 29

    x = -x + 116

    x + x = 116

    2x = 116

    x = 58

    Input your value for x:

    4) 58 + y = 87

    y = 87 – 58

    y = 29

    Solve and check if your values are correct:

    5) 58 + 29 = 89 correct

    58 – 29 = 29 correct
