Track A has 155000 seats and track B has 61000 seats.
Explanation
Suppose, the number of seats at race track B is [tex]x[/tex]
As race track A has 33000 more seats than twice the number of seats at track B, so the number of seats at track A will be: [tex]2x+33000[/tex]
Given that, the total number of seats in two tracks is 216000. So, the equation will be....
[tex]x+(2x+33000)=216000\\ \\ 3x+33000= 216000\\ \\ 3x= 183000\\ \\ x= \frac{183000}{3}=61000[/tex]
So, the number of seats at track B is 61000 and the number of seats at track A [tex]=(2*61000)+33000=155000[/tex]
