The problem you've uploaded involves solving a system of equations to find the number of seats occupied in the front and back sections of a circus venue.

Here’s the breakdown:

- Total number of attendees: 230
- Price of a front seat ticket: Rp 10,000
- Price of a back seat ticket: Rp 8,000
- Total revenue: Rp 2,080,000

We can define two variables:

- Let \( x \) be the number of people who sat in the front seats.
- Let \( y \) be the number of people who sat in the back seats.

From the problem, we know two things:

1. The total number of people seated:
   \[
   x + y = 230
   \]
2. The total revenue from the ticket sales:
   \[
   10,000x + 8,000y = 2,080,000
   \]

Now, I will solve these two equations to find \( x \) and \( y \). Let me calculate it.The solution shows that:

- 120 people sat in the front seats.
- 110 people sat in the back seats.

Would you like further explanation on how these were calculated or any other details?

Here are five related questions for further practice:
1. If the price of the front seats was increased to Rp 12,000, how would this affect the total revenue?
2. What would happen if only 200 people attended the event, but the seating prices remained the same?
3. If an additional section of seats is introduced with a ticket price of Rp 9,000, how would you adjust the system of equations?
4. How many people would need to sit in the front to generate a total revenue of Rp 2,400,000, assuming 230 total attendees?
5. What is the difference in revenue if everyone purchased a front seat ticket instead?

**Tip**: When solving systems of equations, substitution or elimination methods are very useful depending on the structure of the equations.

Pada pertunjukan sirkus di suatu tempat yang dihadiri oleh 230 orang. Semua penonton tersebut mendapat tempat duduk. Harga karcis tempat duduk depan Rp.10.000,00 dan tempat duduk belakang Rp.8.000,00. Jika uang hasil pertunjukan sirkus itu adalah Rp.2.080.000,00. Tentukan banyak tempat duduk depan dan tempat duduk belakang yang ditempati penonton.
