It takes a bear 9 more days to eat a barrel of honey alone than it takes the bear and a second bear to eat the barrel of honey t
ogether. It takes the first bear 7 fewer days to eat a barrel of honey alone than it takes the second bear to eat a barrel of honey alone. In how many days can the two bears eat a barrel of honey together? No links please.
let (x+9)+7=second bear **because we know the second day takes 7 more days to eat the same amount of honey as the first bear**
since the bears can finish a barrel of honey over multiple days, they can only finish part of the barrel of honey in one day.
therefore...
x/(x+9)+x(x+16)=1 or x*1/(x+9)+x*1/(x+16)=1 **the equation equals 1 because you are trying to find how much honey they eat in one day aka 1=single day**
if you solve, you get x=-12; x=12. it can only be the positive value so x=12 is your answer. your welcome fellow rsm students.
