    Explicación paso a paso:

    100-ab – – – – (1)

    100-ba – – – – (2)

    Sumando (1) y (2) sumas hasta 24

    100-ab + 100-ba = 24

    100 + 100 – ab – ba = 24

    200- (10a + b) – (10b + a) = 24

    200-10a-b-10b-a = 24

    200-24 = 10a + 10b + b + a

    176 = 11a + 11b

    176 = 11 (a + b)

    176/11 = a + b

    16 = (a + b)
