Ответ:
42 home team and 33 away team fans attended the game.
Step-by-step explanation:
Let
h denote the number of home team fans a denote the number of away team fans.Since 75 people attended a baseball game and everyone there was a fan of either the home team or the away team; we have
(1) h+a=75.
Since the number of home team fans was 90 less than 4 times the number of away team fans, we have
(2) h=4×a-90
In (1) lets put 4×a-90 instead of h, since h=4×a-90, we have then
4×a-90+a=75
4×a+a=75+90
5×a=165 and finally
a=![\frac{165}{5}=33](/tpl/images/0396/9991/6b03c.png)
We know that h+a=75, if a=33 then h=42
