We are given the professional baseball team won = 84 games.
Let us assume the team loss = x games.
According to problem, "the team won 14 more games than it lost".
14 more than x could be given by expression " x+14".
Therefore, we can setup an equation
x+14 = 84.
Subtracting 14 from both sides, we get
x+14-14 = 84 -14
x = 70.
Team loss = 70 games.
Total number of games played = Number of games win + number of games loss.
= 84 +70 = 154 games.
Therefore, total 154 games were played.
