The outer section has seats arranged in rows of 70 and tickets in this section cost $60 ea
There are 10 more rows in the inner section than that of the outer section

Using the information given- form equations for the seating capacity for the concert hall?
This is an annoying maths question
2. 40x+10=70y-10 => 70y-40x=20?
