Answer:the football team played 25 games in all
Step-by-step explanation:
Let x represent the total number of matches that the football team played.
The football team won 10 matches out of the total number of matches they played. if their win percentage was 40, it means that
10/x × 100 = 40
1000 = 40x
x = 1000/40 = 25
You can say
x+y=5
x=5-y
You know the value of x, put it into the next equation.
3(5-y)-7y=19
15-3y-7y=19
15-19 = 10y
-4=10y
-4/10=y
-2/5=y
Put y value back into either equation to find value of x.
x+y=5
x-2/5=5
x=5+2/5
x=27/5
Therefore, x,y = (27/5, -2/5)
Hope I helped :)
