Scott is reading two books at the same time to prepare for a report he is writing. so far, he has read 407 of the total number o
f 557 pages, which is three-fifths of the shorter book and startfraction 5 over 6 endfraction of the longer book. which system of equations can be used to determine the total number of pages in the shorter book, x, and the total number of pages in the longer book, y? x + y = 557 and three-fifths x + five-sixths y = 407 x + y = 407 and three-fifths x + five-sixths y = 557 x + y = 557 and five-sixths x + three-fifths y = 407 x + y = 118 and startfraction 4 over 9 endfraction x + two-thirds y = 118
