  1. This is easy!!
    Watch!
    a+b=207
    a-b=27
    Ok!Wich means:
    a=207-b
    also
    a=27+b
    207-b=207+b
    207-27=b+b
    180=2b
    b=90
    a=207-b=207-90=117
    And ta ta ta!!!
    The correct answer is:
    a=117
    b=90

  2. Oops! I tough it was
    a+b=207
    a-b=27
    But is a+b=207 and a-b=23. No problem!
    a=207-b
    a=23+b
    207-b=23+b
    207-23=b+b
    184=2b
    b=92
    a=207-b=207-92=115
    Answer: a=115 and b=92
