Answer:
(x,y) = (2,3)
Step-by-step explanation:
y=5x-7 (i)
-3x-2y= -12
-(3x+2y)= -12
3x+2y= 12 (ii)
By putting the value of y from (i) in (ii)
3x+2(5x-7)=12
3x+10x-14=12
13x=12+14
13x= 26
x = 
x= 2
By putting the value of x in (i)
y= 5(2)-7
y= 10-7
y= 3
(x,y) = (2,3)

Answer: $13.70
Step-by-step explanation:
.10* 17= 1.7, because $.10 is charged for everyday the book is late and the books were 17 days late.
1.7* 4= 6.8, because there were four books that were 17 days late.
.10* 23= 2.3, because $.10 is charged for everyday the book is late and the books were 23 days late.
2.3* 3= 6.9, because there were three books that were 23 days late.
6.8+6.9= 13.70 is the amount of money Sydney had to pay the library for her late books.
