Answer: 29000 people went in 1981.

Step-by-step explanation:

Let x= Attendance in 1981.

Given: The average attendance of Everton football club fell by 7% in 1982.

Difference in attendance from 1981 to 1982 = 0.07x

If 2030 fewer people went to matches in 1982,

$0.07 x=2030\\\\\Rightarrow x=\dfrac{2030}{0.07}\\\\\Rightarrow x=29000$

Hence, 29000 people went in 1981.
