the first of two films lasted 9 minutes less than twice as long as the second. the combined length of the two films plus a 5-minute break between them was 260 minutes. how long was the first film?

length of second film --- x minutes
length of first film ---- 2x-9 minutes

x + 5 + 2x-9 = 260
3x = 264
x=88

first film was 2(88)-9 or 167 minutes

check:
88 + 5 + 167 = 260
