Step-by-step explanation:
if x is games won
then games lost is x+14
total no of games=40
x+x+14=40
2x=40-14
x=13 games won
To find y, divide the first equation by 2.
y = 4
To find x, use that value for y in the second equation. Add 4, then divide by 2.
15·4 = 2x -4
60 +4 = 2x
64/2 = x = 32
The solution is (x, y) = (32, 4).
