Can you give me an example of using z3 in python?

z3 is a powerful smt (satisfiability modulo theories) solver developed by microsoft. it can be used to solve a wide range of problems, including its usage with the python programming language.

first, you'll need to install the z3 package using pip:

```bash
pip install z3-solver
```

now, let's create an example of using z3 in python to solve a simple linear equation:

```python
from z3 import *

# create an instance of the z3 solver
solver = solver()

# declare two integer variables x and y
x, y = ints("x y")

# add constraints to the solver
solver.add(x + y == 10)
solver.add(x - y == 2)

# check if the constraints are satisfiable and find a solution
if solver.check() == sat:
    # get a model with the values of x and y
    model = solver.model()
    x_value = model[x].as_long()
    y_value = model[y].as_long()
    print(f"the solution is x = {x_value} and y = {y_value}")
else:
    print("the constraints are unsatisfiable")
```

in this example, we have two linear constraints:

1. x + y = 10
2. x - y = 2

we use the z3 solver to check if the constraints are satisfiable. according to the resulting model, you'll get the solution for `x` and `y`. you should expect the output to be:

```
the solution is x = 6 and y = 4
```

this is a simple example of using z3 in python, and you can use this approach for solving more complex problems!
