The answer that you need is C
So the answer would be A. I had a bit of trouble figuring this out, but then I went to Order of Operations and found it out.
So you fill in n, and I just used 9 since it's in the question. So then, subtract 1 from 9, giving you 8. Then you multiply 0.35 by 8, giving you 2.8. Now lastly, add 7.51, and you get 10.31

X+y=77.95
x-y=30.61
x+x+y-y=108.56
2x=108.56 (divide by 2 both sides of the equation)
x=54.2
y=77.95-x=77.95-54.2=23.67
y=23.67
answer: they are 54.2 and 23.67
Answer:
Try the fourth one. Forgive me if I'm wrong.
