    Alexandera=a

    imani=i

    a is 8 more than i or

    a=8+i

    the sum of the 2 numbers is 50 or

    a+i=50

    a=8+i

    so subsitute 8+i for a in a+i=50

    8+i+i=50

    8+2i=50

    subtract 8 from both sides

    2i=42

    divide both sides by 2

    i=21

    subsiutte into a=8+i

    a=8+21

    a=29

    a=29

    i=21
