Answer:
x=-11/6, y=7/6. (-11/6, 7/6).
Step-by-step explanation:
-2x+2y=6
4x+2y=-5
-----------------
2(-2x+2y)=2(6)
4x+2y=-5
----------------------
-4x+4y=12
4x+2y=-5
----------------
6y=7
y=7/6
4x+2(7/6)=-5
4x+14/6=-5
4x=-5-14/6
4x=-30/6-14/6
4x=-44/6
x=(-44/6)/4
x=(-44/6)(1/4)
x=-44/24
simplify
x=-11/6

Answer: There would be 745 books at the end of month 10.
Step-by-step explanation:
Since we have given that
Number of books initially = 80
Rate of growth = 25% = 0.25
t = 10 months
We need to find the number of books that are expected at the end of month 10.
As we know the formula for "Compound interest":

Hence, there would be 745 books at the end of month 10.
