Answer:
The least common denominator is (b-8)(b+8)(b-1)
Step-by-step explanation:
We are given expression as

Firstly, we will factor both denominators


so, we can plug it back

First term denominator is
(b-8)(b+8)
Second term denominator is
(b+8)(b-1)
So,
Least common denominator will be
(b-8)(b+8)(b-1)
So, we get

D=# of tickets sold at the door
a=# of tickets sold in advance
3a+5d=2630
d=a+30
3a+5(a+30)=2630
8a+150=2630
8a=2480
a=310
d=340
310 tickets were sold in advance and 340 tickets were sold at the door.
