To solve this problem you must apply the proccedure shown below:

1. Let's call the games won
x and the games lost
y.

2. Then, based on the information give in the problem, you can make the following system of equations:


\left \{ {{x=y-2} \atop {x+y=82}} \right.

3. You can use the Substitution method. You must substitute
x=y-2 into the second equation and solve for
y:


(y-2)+y=82


y=42

3. Now substitute this values obtained into the first equation and solve for
x:


x=42-2


x=40

The answer is: The team won 40 games and lost 42 games.
