Question

3. A football club plays some matches during a
season. The club gets 3 points for a win.
2 points for a draw and -1 point for a defeat
Write an expression for the total points
scored (S), if it wins 20 matches, draws y
matches and loses x
matches.​

Answer 1

Answer:

we know that:for win=3,for draw=2,for lose=-1 they won=2 so number of points=20×3=60

draw=y so number of points=y×2=2y

lose=x so number of points=x×-1=-x

we can write expression as 60+2y-x=0

or x-2y=60
