number of textbooks be x

number of library books by y

number of telephone books by z

x+y+z = 36 (#1)

y+x = 2x --- > y = x (#2)

x+z = 3y --- z = 3y - x (#3)

back in #1

x+y+z = 36

x + x + (3y-x) = 36

x+x+(3x-x) = 36

4x=36

x=9

then y=9

z = 18

9 library books

9 textbooks

18 telephone books
