the library has a total collection of 2630 books. the number of nonfiction books is 240 fewer than the number of fiction books but 190 more than the number of picture books. how many books of each type are there in the library?

n=f240
n=p+190
n+f+p = 2630
(f240) + f + (f240190) = 2630
f = 1100
n = 860
p = 670
