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

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

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-2)+y=82

y=42

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

x=42-2

x=40

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