Let h represent number of hits.
Let m represent number of misses.
1) 9h - 7m = 33
2) h - m = 2
2a) h = 2 + m
Sub 2a) into 1)
9*(2+m) - 7m = 33
18 + 9m - 7m = 33
2m = 15
m = 7.5
Sub m = 7.5 into 2a)
h = 2+ 7.5
h = 9.5
Though this does work you can’t exactly shoot a half miss or hit so h=13 and m=12 works as well...
9(13)-7(12)=33
117- 84=33
11y - 22 + 3y = -7y + 14
*combine like terms*
14y - 22 = -7y + 14
21y = 36
y = 36/21 = 12/7 or 1 5/7
hope this helps :)
The set X = { x , {x} } would, I think, fit the Bill
So its 2 elements
I GUESS IT'S CCCCCCC , RIGHT?
