Question

A team has P points.

P = 3W + D

W = Wins
D = Draws

B) After 35 games a different football team has 50 points. 14 games were draw. How many games has this team lost

Answer 1

Sub in the values and solve for W
50=3W+14
50-14=3W
36=3W
12=W
The team won 12 games.
12+14=26 (games drawn and won)
35-26=9
Therefore they lost 9 games

Answer 2

You would just plug it in and solve for w.     

p = 3w + d
50 = 3w + 14          -subtract the 14 from both sides
36 = 3w                  - divide both sides by 3
12 = w

There were 12 wins. If they played 35 games, 12 were won and 14 were draw, you just subtract them from 35 and you get 9. The team lost 9 games.
