22. In a fight betweenSpanishrs, ead English were involved. What
system of equations allows us to determine the number of flies and
spiders that participated in the fight? (Take into account that the fly has 6 legs
and the spider 8).
Am+a =42, 6m + 8a 276
B 6m +a = 42, m + 8a = 276
Cm -a = 42, 6m - 8a 276
Dm +a = 42, 8m + 6a = 27
