Respuesta:
dieciséis
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)
