Melissa scored a total of w points playing some games. Is she scored x points in each game. How many games did she play?
First, we know that Melissa played some games. This is represented by the variable w. 

Second, we know that she scored x points in each game. This is represented by the variable x. 

Now, we just have to put these two pieces of information together to solve for the number of games she played. 

We can do this by setting up the equation: 

w = x * games 

We know w, and we know x, so we can solve for games. 

games = w/x
