Answer and Step-by-step explanation:
I don’t really know which system of equation to use, but I did the work. I also think there is supposed to be an attached picture but it’s fine
——————————————————————————————————————
Let x be students
Let y be adults
x + y = 222
5x + 8y = 1,626. <— let’s use the elimination/addition method to Solve this. Also, let’s eliminate y.
8 (x + y = 222)
-1 (5x + 8y = 1,626)
8x + 8y = 1,776
+ -5x - 8y = -1,626 <— add both of them
——————————————
3x = 150 <— divide 150 by 3
x = 5
