Fiona is serving iced tea and lemonade at a picnic. She has only 44 glasses in which to serve the drinks. If x represents the number of glasses of iced tea and y represents the number of glasses of lemonade, which equation represents the number of glasses of ice tea she can serve?

The 44 glasses are shared between iced tea and lemonade, so the total is x + y = 44. Subtract y, the number of lemonade glasses, from both sides to get x = 44 − y. Therefore, the equation “x is equal to 44 minus y” represents the number of glasses of iced tea she can serve.
