**Reiny**, Sunday, September 30, 2012 at 9:59pmtelephone books --- x

textbooks ----- y

library books 36-x-y

36-x-y + x = 2y or 3y = 36

y = 12

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

y+x = 108 - 3x - 3y

4x + 4y = 108

x+y= 27

but y = 12

so, x + 12 = 27

x = 15

then 36-12-15 = 9

number of telephone books = 15

number of textbooks = 12

number of library books = 9
