9. The administrator of the Wolong Nature Reserve distributed some bamboo to several giant pandas. If each giant panda gets 5 bamboo, there are 11 bamboo left; if the number of giant pandas increases to three times the original number minus 5, and each giant panda gets 2 bamboo, there are 8 bamboo short. Therefore, there are ( ) giant pandas and ( ) bamboo in total.
29
156
【Answer】If the number of giant pandas increases to three times the original, and each giant panda gets 2 bamboo sticks, there would still be a shortage of 18 bamboo sticks; thus, the number of giant pandas is: $(18+11) \div(3 \times 2-5)=29$; substituting this, we get 156 bamboo sticks.
