The image describes a problem about the price of pencils and notebooks in Indonesian. Here’s the breakdown of the problem:

- The price for 4 pencils and 5 notebooks is Rp 23,000.00.
- The price for 2 pencils and 3 notebooks is Rp 13,000.00.
- The task is to find the price of 1 pencil and 1 notebook.

We can solve this using a system of linear equations. Let's define:
- \( p \) as the price of one pencil.
- \( n \) as the price of one notebook.

From the given information, we can form these two equations:

1. \( 4p + 5n = 23000 \)
2. \( 2p + 3n = 13000 \)

I will now solve this system of equations to find \( p \) (price of one pencil) and \( n \) (price of one notebook).The price of one pencil is Rp 2,000.00, and the price of one notebook is Rp 3,000.00.

Would you like more details on the steps taken to solve this? Here are some related questions to explore:

1. How do we solve systems of equations using substitution?
2. What is the graphical representation of these two equations?
3. How can we check if the solution is correct?
4. What are other methods for solving systems of equations (e.g., elimination)?
5. How would the solution change if one of the prices increased?

**Tip**: When solving a system of linear equations, always check if the equations are consistent by substituting the solutions back into the original equations.
