Answer:
y = (10x + 600)/x
Step-by-step explanation:
To find the average cost, we must divide the total cost by the number of people.
The number of meals served will equal the number of people, since everybody gets just 1 meal.
Each meal is 10 dollars, plus the 600 rental fee.
The total cost will be the meal prices plus the fee, all divided by the number of people/number of meals, or x.
(4x - y)/(2y + x) when x = 3 and y = 3 is
(4(3) - 3)/(2(3) + 3) = (12 - 3)/(6 + 3) = 9/9 = 1
So first you would combine the like-terms so you get:

and combine the second like-terms:

now you only have a two step equation and you continue by doing the reciprocal and you add the -1/5 to the 24.8 where you get:
7/9x=24.6
then because the 7/9 is being multiplied by the x and your trying to isolate it you divide it by the 7/9 on both sides and you'll end up getting
x=31.628571429....
