Answer:
D.
Explanation:
x = number of glasses of iced tea
y = number of glasses of lemonade
The total number of glasses is
x + y
The total number of glasses is 44
x + y = 44
This is not a choice, but the answer must be equivalent to this equation.
Solve for x by subtracting y from both sides.
x = 44 - y
