number of pages ---- x

at end of Saturday, number of pages left = x-21

she read 5/9 of those, leaving 4/9(x-21) pages

but this is supposed to be 1/3 of the pages

4/9(x-21) = (1/3)x

times 9

4(x-21) = 3x

4x - 84 = 3x

x = 84

There were 84 pages in the book

check:

she read 21 pages on Saturday leaving 63

on Sunday she read 5/9 of that or 35 pages

leaving her with 28 pages to read

and 1/3 of 84 = 28
