    Answer:

    a + b = 63

    a – b = 12

    So, a – b = 12 which can also be written as a = b + 12

    Then use substitution and plug in (b + 12) for a in the first equation

    (b+12) + b =63

    -12              -12

    ———————

    2b  =  51 so b=25.5

    Now, you know b which can be used to find a

    63- 25.5= 37.5

    So, a = 37.5 and b = 25.5
