# Math via python code with a single agent

The point of this example is to illustrate that for agents that have an AgentExecutor (which most frameworks have apart from Autogen), the approach from MathChat can be done with a single agent, as the second conversation partner there just plays the role of an AgentExecutor.

To solve the system of equations given by:
1. \( 725x + 727y = 1500 \)
2. \( 729x + 731y = 1508 \)
We will use the method of elimination to find the values of \( x \) and \( y \). First, we will eliminate \( y \) by subtracting the first equation from the second. This will give us an equation in terms of \( x \) only.
Let's calculate the coefficients and constants after subtraction:
- Coefficient of \( x \): \( 729 - 725 \)
- Coefficient of \( y \): \( 731 - 727 \)
- Constant term: \( 1508 - 1500 \)
```
Use Tool: python_repl(command="print(729 - 725, 731 - 727, 1508 - 1500)")
```
```

```
From the result of the subtraction, we have the simplified equation:
\[ 4x + 4y = 8 \]
To simplify further, we divide the entire equation by 4:
\[ x + y = 2 \]
Now, we have a new system of equations:
1. \( x + y = 2 \)
2. \( 725x + 727y = 1500 \)
We can solve this system using substitution or elimination. Let's use substitution. We express \( y \) in terms of \( x \) from the first equation:
\[ y = 2 - x \]
Substitute \( y = 2 - x \) into the second equation:
\[ 725x + 727(2 - x) = 1500 \]
Expanding and simplifying this equation will give us the value of \( x \). Let's calculate it:
```
Use Tool: python_repl(command="from sympy import symbols, Eq, solve; x = symbols('x'); eq = Eq(725*x + 727*(2 - x), 1500); solve(eq)")
```

Final Answer: To solve the system of equations given by:
1. \( 725x + 727y = 1500 \)
2. \( 729x + 731y = 1508 \)
We first subtract the first equation from the second to eliminate \( y \), resulting in:
\[ 4x + 4y = 8 \]
which simplifies to:
\[ x + y = 2 \]
Using this in conjunction with the first equation, we substitute \( y = 2 - x \) into \( 725x + 727y = 1500 \) to get:
\[ 725x + 727(2 - x) = 1500 \]
Solving this equation gives \( x = -23 \).
Substituting \( x = -23 \) back into \( x + y = 2 \), we find:
\[ -23 + y = 2 \]
\[ y = 25 \]
Thus, the values are:
\[ x = -23, \quad y = 25, \quad x - y = -23 - 25 = -48 \]
Therefore, \( x = -23 \), \( y = 25 \), and \( x - y = -48 \).

To solve the system of equations given by:

2. \( 729x + 731y = 1508 \)

We first subtract the first equation from the second to eliminate \( y \), resulting in:

\[ 4x + 4y = 8 \]

which simplifies to:

\[ x + y = 2 \]

Using this in conjunction with the first equation, we substitute \( y = 2 - x \) into \( 725x + 727y = 1500 \) to get:

\[ 725x + 727(2 - x) = 1500 \]

Solving this equation gives \( x = -23 \).

Substituting \( x = -23 \) back into \( x + y = 2 \), we find:

\[ -23 + y = 2 \]

\[ y = 25 \]

Thus, the values are:

\[ x = -23, \quad y = 25, \quad x - y = -23 - 25 = -48 \]

Therefore, \( x = -23 \), \( y = 25 \), and \( x - y = -48 \).
