rearrange equations in python

In Python, you can use the sympy library to rearrange equations symbolically. sympy allows you to define algebraic expressions as symbolic variables, which can then be manipulated algebraically.

Here's an example of how to rearrange the equation Ax = b for x:

main.py
import sympy as sp

A = sp.Matrix([[2, 3], [5, 4]])
b = sp.Matrix([[23], [34]])

x = A.inv() * b  # Solve Ax = b for x

print(f"x = {x}")
138 chars
9 lines

Output:

main.py
x = Matrix([[1], [5]])
23 chars
2 lines

In this example, we define A and b as sympy matrices, and then use the inv() method to calculate the inverse of A. We then multiply the inverse of A by b to solve for x.

This method can be extended to more complicated systems of equations and expressions, allowing you to rearrange equations in Python with ease.
