Answer:

Explanation:
Let x represents the number of glasses of iced tea and y represents the number of glasses of lemonade.
We have been given that Fiona is serving iced tea and lemonade at a picnic. She has only 44 cups in which to serve the drinks. We can represent this information in an equation as:

Since x represents the number of glasses of iced tea, so we will solve for x by subtracting y from both sides of our equation.


Therefore, the equation
represents the number of glasses of iced tea Fiona can serve.
