Question

Linear equation help, PLS more detals and clearly to see. If you don't know python, you can ignore the part C

Below is the transcription of the given code snippet, which is intended for educational purposes on solving a system of linear equations using Python's `numpy` library.

---

**Educational Code Example: Solving Linear Equations**

In the code cell provided, we are tasked with completing the code required for part C. The code uses the `numpy` library to solve a system of linear equations.

```python
import numpy as np

A = ...
b = ...
x = np.linalg.solve(..., ...)
print("x1 is", x[0], "and x2 is", x[1])
```

**Explanation:**

- **import numpy as np**: This line imports the `numpy` library, which provides support for large, multi-dimensional arrays and matrices, along with mathematical functions to operate on these arrays.

- **A = ...** and **b = ...**: Here, `A` represents the coefficient matrix, and `b` represents the constant matrix (or vector). You need to replace `...` with the specific values or arrays.

- **x = np.linalg.solve(..., ...)**: This function is used to find the solution `x` to the linear equation system `Ax = b`. You must fill in the missing arguments with your defined matrices `A` and `b`.

- **print("x1 is", x[0], "and x2 is", x[1])**: This statement prints the solutions `x1` and `x2`, which correspond to the elements of solution vector `x`.
