20/x+11=10/x+3
20(x+3)=10(x+11)
20x + 60 = 10x + 110
10x = 50
x = 5

Step-by-step explanation:
Longest book: 396 Shortest book: 1/4×396=99 Middle book: 3×99= 297
<span>
If the book in the middle of her shelf has three times the number of pages of the shortest book then how many pages does the middle book have?
Answer: 297</span>
13x - 6y = 22
x - y = 6
6(x-y) = 6*6
6x - 6y = 36
subtract both the equations
13x - 6x -6y + 6y = -14
7x = -14
x = -2
13*-2 -6y=22
-26 -6y=22
-6y = 48
y = -8
answer: x = -2
y = -8
